the probability of winning a game is 25%. how many times should you expect to win if you play 20 times.
That would be 5.
thank you
It’s 10 times
.25 times 20
or 1/4 times 20
yes.
yes
the probability of winning a game is 25%. how many times should you expect to win if you play 20 times.
To find out, you can multiply the probability of winning (0.25) by the number of times you play (20):
0.25 * 20 = 5
So, you would expect to win about 5 times if you play 20 times.
. A survey showed that 62% of car owners prefer two car door 26% prefer four door cars, and 12% have no preference you ask 400 people how many do you think prefer the two car door.
126 people
152 people
196 people
248 people
Out of 400 people, 62% prefer two car doors. To find out how many people that is, you can multiply:
0.62 x 400 = 248
So, you can expect around 248 people to prefer the two car door out of the 400 surveyed. Therefore, the correct answer is 248 people.
Tony works in a factory that produces 1,000 computers each day. When 50 computers were sampled, it was fount that 7 were defective. Estimate how many defective computers are made each day.
what is it??
To estimate the number of defective computers produced each day, you can use a proportion based on the sample:
7/50 = x/1000
Solving for x, which represents the estimated number of defective computers produced daily:
(7/50) * 1000 = 140
So, you can estimate that the factory produces around 140 defective computers each day.
The spinner is divided into equal part. Use a tree diagram to find the probability that the spinner will land on a consonant both times if the spinner is spun twice
I'm sorry, as an AI language model, I am not able to create a visual tree diagram. However, I can help you to solve the problem.
Assuming that the spinner has six equal parts and three of them have consonants (C) - let's say they are red, and the other three (let's say green) have vowels (V), you can create a tree diagram to figure out the probability of spinning a consonant twice:
First spin:
- C (red): 3/6 probability
- C (red): 2/5 probability
- V (green): 3/5 probability
- V (green): 3/6 probability
- C (red): 3/5 probability
- V (green): 2/5 probability
The probability of getting a consonant on both spins can be calculated as the product of each event's probability:
P(C, C) = (3/6) * (2/5) = 0.2
Therefore, the probability of spinning a consonant both times if the spinner is spun twice is 0.2 or 20%.
A:1/9
B:1/3
C:3/4
D:5/9
these are the answer choices and the tree diagram is N,E,U
