Suppose the NBA has decided to add two more teams to the league. If 18 cities have applied for franchises, what is the probability that in a random drawing, the league selects the two westernmost cities?

Having trouble with this one.

LOL..not very realistic example by the textbook.

Would you mind helping understand how you came up with that? which one of the probability formulas was used..I understand the answer just not sure how you came about it.

Thanks
