Two cards are drawn at random from a pack of 52 cards. What is the probability that the drawn cards are both aces?
Correct Answer: 1/221
Explanation:
n(S) = Number of ways of drawing 2 cards out of 52 52C2 = (52 x 51) / (2 x 1) = 1326
n(E) = Number of ways of drawing 2 cards out of 4
= 4C2 = (4 x 3)/2 = 6
∴ P(E) = 6/1326 = 1/221
