Rhee and Pamela are two of the five members of a band. Every week, the band picks two members at random to play on their own for five minutes. What is the probability that Rhee and Pamela are chosen this week?

If they are independently chosen, pr(R,P)=2/5*1/4=1/10
Ohh ok thank you! God bless you
Wait why times 1/4?
of the first choice, there are either of two of the five (2/5) which are acceptable. Then, of the four remaining, only one is acceptable (1/4). Joint probability is (2/5)(1/4)=2/20=1/10
Ohh ok, thank you!!!
