The table shows the snack preferences of 50 shoppers at the mall. What is the probability that one shopper, selected at random from the 50 surveyed, preferred the potato chips or pretezels?
Food Number of shoppers
Fruit snacks 9
Potato chips 12
Apple 3
Pretzels 14
Water 12
Answer choices
1/5
13/25
1/10
18/25
The probability that one shopper, selected at random from the 50 surveyed, preferred the potato chips or pretzels is (12+14)/50 = 26/50 = 13/25.
Therefore, the correct answer is 13/25.
A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 4.
Answer choices
1/4
1/3
1/2
2/3
There are three numbers less than 4 on a standard number cube (1, 2, and 3), out of a total of six possible outcomes.
Therefore, the probability of rolling a number less than 4 is 3/6, which simplifies to 1/2.
So, the answer is 1/2.
To find the probability of the pointer landing on G, we need to determine the number of favorable outcomes (the number of times the pointer lands on G) and the total number of possible outcomes (the total number of sections on the spinner).
From the spinner provided, we can see that there is only 1 section labeled G, and there are a total of 8 sections on the spinner (4 R's, 2 B's, 1 G, and 1 Y).
Therefore, the probability of the pointer landing on G is 1 out of 8, which can be simplified to 1/8.
So, the correct answer is 1/8.
To determine the probability of the pointer landing on G, we need to consider the total number of possible outcomes and the number of outcomes leading to G.
In this case, the spinner has a total of 8 sections: R, R, R, R, B, B, G, and Y. Since each section is equally likely to be landed on, the total number of possible outcomes is 8.
Now, let's look at the number of outcomes leading to G. There is only 1 G section on the spinner. Hence, the number of outcomes leading to G is 1.
To calculate the probability, we divide the number of outcomes leading to G by the total number of possible outcomes:
Probability = Number of outcomes leading to G / Total number of possible outcomes
Probability = 1 / 8 = 1/8
So, the probability of the pointer landing on G is 1/8.
Therefore, the correct answer choice is 1/8.
