Jerry mixes the letters F, P, M, M, M, F, P, and J thoroughly. Without looking, Amanda draws one letter. Expressed as a fraction, decimal, and percentage, what is the probability that J will not be the letter Amanda selects?
A. seven-eighths, 0.875, 87.5%***
B. The fraction is 5 over 8., 0.625, 62.5%
C. one-eighth, 0.125, 12.5%
D. The term shows 8 over 7., 1.14, 11.4%
You are correct! The probability of selecting J is 1/8. The probability of not selecting J is 1 - 1/8 = 7/8.
Expressed as a fraction, the probability that J will not be selected is 7/8.
As a decimal, it is 0.875.
As a percentage, it is 87.5%.
So the correct answer is A. Seven-eighths, 0.875, 87.5%.
Christopher mixes the letters S, E, L, E, C, T, E, and D thoroughly. Without looking, Allen draws one letter. Expressed as a fraction, decimal, and percentage, what is the probability that Allen will not select a consonant?
A. three-eighths, 0.375, 37.5%
B. start fraction 3 over 5 end fraction, 0.6, 60%
C. start fraction 5 over 8 end fraction, 0.625, 62.5%
D. one-half, 0.5, 50%
The consonants are S, L, C, T, and D. There are five consonants in the set. The remaining three letters are vowels, which Allen does not want to select.
The probability of Allen selecting a consonant is 5/8.
The probability of Allen not selecting a consonant (i.e., selecting a vowel) is 1 - 5/8 = 3/8.
Expressed as a fraction, the probability is 3/8.
As a decimal, it is 0.375.
As a percentage, it is 37.5%.
Therefore, the correct answer is A. Three-eighths, 0.375, 37.5%.
Suppose you have a drawer full of white, black, and yellow pairs of socks. If the probability of picking a white pair of socks is four-ninths, and the probability of picking a black pair of socks is
start fraction 7 over 18 end fraction, what is the probability of picking a yellow pair of socks?
A. start fraction 1 over 6 end fraction
B. Start Fraction 5 over 12 End Fraction
C. Start Fraction 7 over 15 End Fraction
D. Start Fraction 16 over 27 End Fraction
Since the sum of the probabilities of picking white, black, and yellow socks must be equal to 1 (i.e., 100%), we can find the probability of picking a yellow pair of socks by subtracting the sum of the probabilities of picking white and black socks from 1.
Therefore, the probability of picking a yellow pair of socks is:
1 - (4/9 + 7/18) = 1 - (8/18 + 7/18) = 1 - 15/18 = 3/18 = 1/6.
So the answer is A. Start fraction 1 over 6 end fraction.
The sample space for a roll of two number cubes is shown in the table.
A 6 by 6 table of ordered pairs is shown.
• A single ordered pair appears in each cell of the table.
In row one, the first element of each ordered pair is 1. This pattern continues through row 6, where the first element in each ordered pair is 6.
• In column one, the second element in each ordered pair is 1. This pattern continues through column 6, where the second element in each ordered pair is 6.
What is the probability that the roll will result in one even and one odd number?
A. one-ninth
B. one-fourth
C. one-third
D. one-half
First, we need to count how many outcomes result in one even and one odd number. An even number can be obtained in three ways (2, 4, or 6) and an odd number can be obtained in three ways (1, 3, or 5). Thus, the total number of outcomes that result in one even and one odd number is 3 x 3 = 9.
Since there are a total of 6 x 6 = 36 possible outcomes from rolling two number cubes, the probability of rolling one even and one odd number is 9/36 = 1/4.
So the answer is B. One-fourth.
My bad I put it again
No problem, let me know if you have any other questions.
The two numbers rolled can be added to get a sum. Find P(sum is even).
A. one-fourth
B. start fraction 15 over 36 end fraction
C. one-half
D. start fraction 3 over 4 end fraction
We can determine whether the sum of two numbers is even or odd by looking at the sum of their individual parities (even or odd).
For the sum of two numbers to be even, both numbers must be even or both numbers must be odd.
We can roll an even number in three ways (2, 4, or 6), and an odd number can be rolled in three ways (1, 3, or 5). Therefore, the probability of rolling an even number is 3/6 = 1/2, and the probability of rolling an odd number is also 3/6 = 1/2.
The probability of rolling two even numbers is (1/2) x (1/2) = 1/4, since there are two independent events. The probability of rolling two odd numbers is also 1/4.
Therefore, the probability of rolling an even sum is:
P(two even numbers) + P(two odd numbers) = 1/4 + 1/4 = 1/2.
So the answer is C. One-half.
You are packing for a vacation. You pack 3 pairs of shorts, 5 shirts, and 2 pairs of shoes. How many different outfits will you be able to make using one pair of shorts, one shirt, and one pair of shoes?
A. 10
B. 17
C. 30
D. 35
I think It's 30?
You are correct! To find the number of outfits, we multiply the number of choices for each article of clothing together:
3 choices of shorts x 5 choices of shirts x 2 choices of shoes = 30
So the answer is C. 30.
A spinner has 3 equal sections: red, white, and blue. John spins the spinner and tosses a coin. Which shows the sample space for spinning the spinner and tossing the coin?
A. A table with 3 rows and 4 columns is shown.The second column of the first row reads Red. The third column of the first row reads White. The fourth column of the first row reads Blue. The first column of the second row reads Heads. The second column of the second row reads Heads, Red. The third column of the second row reads Heads, White. The fourth column of the second row reads Heads, Blue. The first column of the third row reads Tails. The second column of the third row reads Heads, Red. The third column of the third row reads Heads, White. The fourth column of the third row reads Heads, Blue.

The second column of the fifth row has the number 96. The first column of the sixth row reads 1950 dash 2000. The second column of the sixth row has the number 110.
B. A table with 3 rows and 3 columns is shown.The second column of the first row reads Red. The third column of the first row reads White. The first column of the second row reads Heads. The second column of the second row reads Heads, Red. The third column of the second row reads Heads, White. The first column of the third row reads Tails. The second column of the third row reads Heads, Red. The third column of the third row reads Heads, White.
C. A table with 2 rows and 4 columns is shown.The second column of the first row reads Red. The third column of the first row reads White. The fourth column of the first row reads White. The first column of the second row reads Heads. The second column of the second row reads Heads, Red. The third column of the second row reads Heads, White. The fourth column of the second row reads Heads, Blue.
D. A table with 3 rows and 4 columns is shown.The second column of the first row reads Red. The third column of the first row reads White. The fourth column of the first row reads Blue. The first column of the second row reads Heads. The second column of the second row reads Heads, Red. The third column of the second row reads Heads, White. The fourth column of the second row reads Heads, Blue. The first column of the third row reads Tails. The second column of the third row reads Tails, Red. The third column of the third row reads Tails, White. The fourth column of the third row reads Tails, Blue.
The sample space for spinning the spinner and tossing the coin can be shown in a table with 3 rows and 4 columns, which is option D:
The second column of the first row reads Red.
The third column of the first row reads White.
The fourth column of the first row reads Blue.
The first column of the second row reads Heads.
The second column of the second row reads Heads, Red.
The third column of the second row reads Heads, White.
The fourth column of the second row reads Heads, Blue.
The first column of the third row reads Tails.
The second column of the third row reads Tails, Red.
The third column of the third row reads Tails, White.
The fourth column of the third row reads Tails, Blue.
Each cell in the table represents one possible outcome when spinning the spinner and tossing the coin. For example, the outcome of spinning red and tossing heads would be represented by the cell in the second column of the second row (Heads, Red).
The probability it will snow in the next two weeks is start fraction 1 over 12 end fraction for this week and one-fourth for next week. What is P(snow this week, then snow next week)?
A. one-eighth
B. one-sixteenth
C. Start Fraction 1 over 24 End Fraction
D. Start Fraction 1 over 48 End Fraction
To find the probability of two independent events both occurring, we multiply their probabilities together.
The probability of it snowing this week is 1/12, and the probability of it snowing next week is 1/4. Therefore, the probability of snowing this week and next week is:
P(snow this week, then snow next week) = P(snow this week) x P(snow next week)
P(snow this week, then snow next week) = (1/12) x (1/4)
P(snow this week, then snow next week) = 1/48
So the answer is D. Start Fraction 1 over 48 End Fraction.
Eric has two identical number cubes. The faces of each cube are numbered 1–6. Eric will roll both of the number cubes at the same time. What is the probability that both of the numbers showing face-up will be multiples of 3?
A. two-ninths
B. one-third
C. start fraction 1 over 6 end fraction
D. one-ninth
A number is a multiple of 3 if and only if the sum of its digits is a multiple of 3.
The only possible rolls that satisfy this condition are (3, 3) and (6, 6).
Since there are 6 x 6 = 36 possible outcomes when rolling two dice, the probability of rolling a (3, 3) or a (6, 6) is 2/36 = 1/18.
Therefore, the answer is D. One-ninth.
So 1 over 9 or 1 over 3
The correct answer is 1/9.
Write the number of permutations in factorial form. Then simplify.
How many different ways can you and five friends sit in your assigned seats when you go to a concert?
A. 6!; 120
B. 6!; 720
C. 5!; 120
D. 5!; 30
The number of ways to arrange 6 people in a line is given by the formula 6!, which represents the number of permutations of 6 objects.
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720
So the answer is B. 6!; 720.
When buying a new car, you have a choice of 4 different models, 3 different colors, and 2 different sizes. How many choices are there for one car?
A. 5
B. 12
C. 16
D. 24***
Can you check this, I think it's 24.
You are correct! To find the number of choices of one car, we multiply the number of choices for each attribute (model, color, and size) together:
4 choices of model x 3 choices of color x 2 choices of size = 24
So the answer is D. 24.
There are 20 entries in the chess tournament. How many ways can the entries finish in first, second, and third place?
A. 340
B. 6,840
C. 7,220
D. 8,350
The number of ways the 20 entries can finish in first, second, and third place, assuming all entries are distinct, is given by the formula:
20 x 19 x 18 = 6,840
So the answer is B. 6,840.
A bag contains tiles with the letters P-R-O-B-A-B-I-L-I-T-Y. Tyler chooses a tile without looking and doesn’t replace it. He chooses a second tile without looking. What is the probability that he will choose the letter I both times?
A. one over fifty-five
B. two over fifty-five
C. two over one hundred twenty-one
D. three over one hundred twenty-one
There are 13 letters in the word "PROBABILITY" and 2 of them are "I"s.
After Tyler chooses one tile, there are only 12 tiles left, including only 1 "I". So the probability of choosing an "I" on the second draw, given that he chose an "I" on the first draw and did not replace it, is 1/12.
Therefore, the probability of choosing an "I" on both draws is:
P(I, then I) = P(I on first draw) x P(I on second draw, given I on first draw)
P(I, then I) = 2/13 x 1/12
P(I, then I) = 1/78
So the answer is not listed, but it is equivalent to A. One over fifty-five.
thanks I just need to check I only have a couple questions left
You're welcome! Feel free to ask any questions you have left.
A sandwich shop offers the following toppings. How many two-topping sandwiches can you make?
lettuce
tomato
bacon
cheese
mustard
A. 8
B. 10
C. 12
D. 20
To find the number of two-topping sandwiches that can be made, we need to use the combination formula:
n! / (r! * (n-r)!)
where n is the total number of toppings and r is the number of toppings we are choosing.
Using this formula, we get:
6! / (2! * (6-2)!) = 6! / (2! * 4!) = (6 x 5) / (2 x 1) = 15
So there are 15 different two-topping sandwiches that can be made.
Therefore, the answer is not listed, but it is closest to B. 10.

Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes? Explain
I need a little help with this question Bot
To solve this problem, we need to compare the probabilities of winning the grand prize using each method.
Method 1: Spinning the wheel
Since there are 6 equal sections labeled
