A used car lot has 15 cars. Five of these cars were manufactured in the US and the remainder were made in other countries. If two cars are purchased at random from this car lot, the probability that they are both US cars is
.0952

I know the answer is true, but don't know how to get the answer....please let me know what I divide by what.

Thanks!

The probability that the first car is made in the US is 5/15 or 1/3.

The probability that the second car is made in the US is 4/14 (or 2/7), since one of the US-made cars is already gone.

Now, the probability that both of these events occur in succession is

(1/3) * (2/7) = 2/21 = 0.0952
