Standard deck of 52 cards. 2 cards are dealt WITHOUT replacement. What is the probability that both cards are Queens given that one of them is the Queen of Clubs.
Conditional Probability.
P(Two Queens | Queen of Clubs) = P(Two Queens AND Queen of Clubs) / P(Queen of Clubs)
P(Two cards of the same face value) = (4/52)(3/51) = 1/221
Stuck.
