The probability that the grocery bill for a customer is greater than $100 (event H) is .55. The probability that a customer pays with a credit or debit card given that his or her grocery bill was greater than $100 is .85.

(2) What is the probability that a customer’s grocery bill was over $100 given that he or she paid with a credit or debit card?
(3) In this problem, are C and H independent? Explain
