Question
Two cards are drawn at random from a standard deck of 52
cards. What is the probability of drawing at least one queen?Solution
Case 1: There is 1 queen
Required probability = (4C1 × 48C1)/52C2 = 32/221
Case 2: There are 2 queens
Required probability = 4C2/52C2 = 1/221
Therefore, desired probability = (32/221) + (1/221) = 33/221
