find the chance of a king

Question

. Two cards are drawn in succession from a pack of 52 cards. Find the chance that the first is a king and second a queen if the first card is (i) replaced, (ii) not replaced.

Answer 1

P(K, then Q, w/ replacement) = (1/13)²

 

P(K, then Q, w/o replacement) = (1/13)(4/51)
