Question
At the mall, buying a pair of shoes and buying a book are independent events.The probability that a shopper buys shoes is 0.12. The probability that a shopper buys a book is 0.10.What is the probability that a shopper buys shoes and a book?A.0.02B.0.22C.0.012D.0.12
Solution
The probability of two independent events both occurring is the product of their individual probabilities.
So, the probability that a shopper buys shoes and a book is the product of the probability that a shopper buys shoes and the probability that a shopper buys a book.
This is calculated as follows:
0.12 (probability of buying shoes) * 0.10 (probability of buying a book) = 0.012
So, the answer is C. 0.012.
