Question 585103: A man has 11 pairs of socks in his sock drawer: 3 brown, 6 black, and 2 blue.
a): if the man reaches into his drawer with his eyes closed what is the fractional probability that the pair of socks he chooses is black?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
a)
P(2 black socks) = P(Black Sock AND Black Sock)
P(2 black socks) = P(Black Sock)*P(Black Sock)
P(2 black socks) = (6/11)*(5/10)
P(2 black socks) = 30/110
P(2 black socks) = 3/11
So the answer is 3/11
