<PRE><B>Question 481957</B>
Ten students are being interviewed for a class office. Six of them are female and four are male. Their names are all placed in a box and two students are selected for the interviews. 
a. What is the probability that both of those selected are female?
Ans: 6C2/10C2 = 15/45 = 1/3
------------------------------------- 
b. What is the probability that at least one is male?
P(at least one male) = 1 - P(both are female) = 1-1/3 = 2/3
