Given the statement:
The probability that 20 or fewer kids in a group of 25 like pizza is 57%.
Determine the probability that at least 21 kids in the group like pizza.
Explanation:
The question is kinda tricky, but we can already determine the answer since it is already provided. It is said 20 or fewer kids in a group of 25 who like pizza is 57%, hence we are asked to find the probability that at least 21 kids in the group like pizza, therefore, we simply need to subtract 100% by 57%.
Solution:
= 100% - 57%
= 43%
Final answer:
A. 43%
