Question

Out of 100 gas station customers 80 customers pay with a credit card. Twenty-five gas station customers buy something other than gas (e.g., chips or pop) and 20customers pay with a credit card and buy something other than gas.
If a station customer buys something other than gas, what is the probability that he/she pays with a credit card? If the customer pays with a credit card, what is the probability that he/she buys something other than gas? Are paying with a credit card and buying something other than gas related?
