Question 1046053: Two cards are drawn at random one after another without putting them back from a box with a pack of 4 Jacks and 4 Queens. Find the probability that the first card is a Jack GIVEN THAT both cards are Jacks. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! 4 Jacks and 4 Queens
draw two
P( 2 Jacks) = (1/2)(3/7) = 3/14
P(A|B) = P(A and B)/P(B) Bayes Theorem
P(2nd a J| 1st a J) = (3/14) /(1/2) = 3/7
