Question

A fruit basket contains 9 apples, 5 bananas, 1 orange, and 5 peaches. Kirsten picked a banana out of the basket. She looked at it, noticed it had a big bruise on it, so she put it back in the basket. She then picked an apple as her snack. Find P(banana, apple)

Answer 1

9/20

Explanation:

This is a probabilty, problem

firstly, let us bring out the sample space and size

the sample space is

9 apples,

5 bananas,

1 orange, and

5 peaches

The sample size is (9+5+1+5)= 20

The probability of picking a banana is

Pr(banana) =5/20

=1/4

The probability of picking an apple

Pr(apple) = 9/20

The probability of picking up a banana and an apple with replacement is

=1/4+9/20

=9/80
