You can put this solution on YOUR website! If two different students are randomly selected from a class of 12 boys and 8 girls, what is the probability that both students are girls.
----
# of ways to succeed: 8C2 = (8*7)/(1*2) = 28
------------
# of possible outcomes: 20C2 = (20*19)/(1*2) = 190
----
P(2 girls) = 28/190 = 0.1474
