It is important to know that probability is the ratio between the possible events and the total number of outcomes.

Having said that, the probability would be


P=(13)/(30)\cdot(17)/(29)=(221)/(870)\approx0.25

Hence, the probability 25%, approximately.

It's important to know that the events are dependent because the total number of outcomes changes after selecting the first student.
