At a certain gas station, 40% of the customers use regular gas (A,), 35% use plus gas (A,), and 25% use premium (A). Of those customers using regular gas, only 10% fill their tanks (event B). Of those customers using plus, 20% fill their tanks, whereas of those using premium, 50% fill their tanks. (a) What is the probability that the next customer will request plus gas and fill the tank (A, n B)? 0.07 (b) What is the probability that the next customer fills the tank? 0.609 (c) If the next customer fills the tank, what the probability that regular gas is requested? (Round your answer three decimal places.) 0.048 If the next customer fills the tank, what the probability that plus gas is requested? (Round your answer to three decimal places.) 0.609 If the next customer fills the tank, what is the probability that premium gas is requested? (Round your answer to three decimal places.) 0.609
