Two students are selected at random from a class of 13 males and 7 females. Find the probability that both students are males.
----------------------------
# of ways to pick 2 males: 13C2 = 78
-----
# of ways to pick 2 students randomly: 20C2 = 190
-----------------------------------
Probability of selecting 2 males: 78/190 = 0.4105
