Answer 1

0.8

Explanation:

Event that they bought a burger = A

Event that they purchased fries = B

45% of the customers purchase cheeseburgers.

80% of the customers purchase fries.

Since 80% of the customers purchase fries, if a customer is selected at random:

The probability that they purchased fries, P(B) = 80% or 0.8.
