The probability that the next customer will request mid-grade gas and fill the tank is 0.1800

Step-by-step explanation:

In order to calculate the probability that the next customer will request mid-grade gas and fill the tank we would have to make the following calculation:

probability that the next customer will request mid-grade gas and fill the tank = percentage of the people using mid-grade gas * percentage of the people using mid-grade gas that fill their tanks

probability that the next customer will request mid-grade gas and fill the tank = 30%*60%

probability that the next customer will request mid-grade gas and fill the tank = 0.1800

The probability that the next customer will request mid-grade gas and fill the tank is 0.1800
