In a certain lot, there are 16 white, 7 red, 8 blue, and 9 black cars. You randomly pick a set of keys to one of the cars. What is the probability of choosing a set of keys to a blue car?

Our total cars are:
Total Cars = White Cars + Red Cars + Blue Cars = Black Cars
Total Cars = 16 + 7 + 8 + 9
Total Cars = 40

P(Blue) = Blue Cars / Total Cars
P(Blue) = 8/40

Using our fraction simplify calculator, we get:
P(Blue) = 1/5
