Well, the random variable in this case is the number of girls, denoted by x. Its possible values are 0, 1, 2, and 3. And yes, its values are numerical because they represent a count or quantity. Though, I must say, it seems like those girls are quite popular with a probability of 0.375! Maybe they have a coupon code or something.
