If the probability that 20 or fewer kids in a group of 25 like pizza is 57%, what is the probability that at least 21 kids in the group like pizza? a. 43% b. 25% c. 21% d. 57%

A

Step-by-step explanation:

The total probability of an experiment is always 1.

There are 25 kids, so Probability of 20 or fewer kids  ADDED to the probability of atleast 21 kids will be equal to 1 !!

Given Probability of 20 or fewer kids liking pizza is 57%

Hence Probability of atleast 21 kids liking pizza will be 1 - 57%

So, probability that at least 21 kids in the group like pizza is 43%

Answer choice A is right.
