To determine the probability that the car from Sanger's auto garage needs an oil change and also tire rotation, we multiply the probability of the first event and the second event. We get an equation of,
= (3/5) x (4/7) = 12/35
Thus, the probability that the car needs both oil change and tire rotation is 12/35.
