Assume for this problem that the company has 8 Chevrolets and 4 Jeeps, and two cars are selected randomly and given to sales representatives.

What is the probability of both cars being Chevrolets, given that both are of the same make?

I have tried many different things, but I do not even understand the question. I am assuming make refers to either a Jeep or a Chevrolet, so for each I am assigning them a Pr of 1/2. The union of both cars being chevrolets and being of the same make should be 2/8? I think this because it is a Chevrolet, and among Chevrolets there are 8 and you can only pick out 2...? I am totally lost
