Question

Apples are in 1/4 of all the lunch bags that are distributed at a school picnic, and bananas are in 1/3 of the bags. What is the probability of randomly choosing a lunch bag that contains either an apple or banana?

Answer 1

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana

Explanation:

We have these following probabilities:

1/4 probability that a lunch bag contains an apple.

1/3 probability that a lunch bag contains a banana.

What is the probability of randomly choosing a lunch bag that contains either an apple or banana?

`P = (1)/(4) + (1)/(3) = (3 + 4)/(12) = (7)/(12)`

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana
