You can put this solution on YOUR website! Consider a political discussion group consisting of 7 democrats, 7 republicans, and 4 independents. Suppose that 2 group members are randomly selected, in succession, to attend a political convention. Find the probability of selecting 2 democrats.
------------------
# of ways to select 2 democrats: 7C2 = 21
---
# of ways to select 2 randomly: 18C2 = (18*17)/2 = 153
---
P(select 2 dems) = 21/153
