Hi there!

The probability of choosing the first girl would be 18/30.

The probability of choosing the second girl would be 17/29.

The probability of choosing both girls would be 51/145 because 18/30 x 17/29 is 306/870 simplified to 51/145.

So the probability of choosing both girls would be 51/145.

Hope this helps :D

18+12=number of students in his class (30)
probability that they are girls is 18(#of girls)/30(total students)
