Question

A pineapple chew was selected 8 times.
A cherry chew was selected 25 times.
A peach chew was selected 24 times.

If the experiment is repeated 400 more times, about how many times would you expect Shandra to remove a pineapple chew from the bag? Round your answer to the nearest whole number.

Answer 1

From her experiment:
prob(pine) = 8/57
prob(cherry) = 25/57
prob(peach) = 24/57

expect (8/57)(400) pineapples to be picked, or appr 56 times
