Answer 2

B. The probability of buying bread and cheese is 0.15

Explanation:

Data

• probability that a shopper buys bread, P(A) = 0.6

• probability that a shopper buys cheese, P(B) = 0.25

If two events A and B are independent, then the probability that A and B occur is:

P(A∩B) = P(A)*P(B)

Replacing with data:

P(A∩B) = 0.6*0.25 = 0.15
