The probability of buying bread and cheese is 0.15

What is Probability?

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcome's relative likelihoods and distribution.

Step-by-step explanation:

Data

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

probability that a shopper by cheese, p(B) = 0.25

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

P(AUB) = P(A)*P(B)

Replacing with data

P(A∩B) = 0.6*0.25 = 0.15
