At a gas station, 40% of the customers use regular gas (A1), 35% use midgrade gas (A2), and 25% use premium gas (A3). Of those customers using regular gas, only 30% fill their tanks (event B). Of those customers using midgrade gas, 60% fill their tanks, whereas of those using premium, 50% fill their tanks. (a) What is the probability that the next customer will request midgrade gas and will fill the tank? (b) What is the probability that the next customer will fill the tank?
