Question 651419: there is a group consisting of 9 Democrats, 9 Repubicans and 2 Independents.
Suppose that 2 group members are selected at random and in succession.
Find the probability of selecting 2 independents.
Do I use nPr to solve with 20P2? Or how do I solve this?

there is a group consisting of 9 Democrats, 9 Repubicans and 2 Independents.
Suppose that 2 group members are selected at random and in succession.
Find the probability of selecting 2 independents.
------
# of ways to succeed: 2C2 = 1
---
# of possible outcomes: 20C2 = 190
---
P(select 2 independents) = 1/190 = 0.0053
