From a pack of 52 cards, two cards are drawn together at random. What is the probability of both the cards being kings?

Correct Answer: 1 221

Explanation:

Let S be the sample space.



Then, n(S) = 52C2 = (52 x 51) = 1326.
(2 x 1)


Let E = event of getting 2 kings out of 4.



n(E) = 4C2 = (4 x 3) = 6.
(2 x 1)



∴ P(E) = n(E) = 6 = 1 .
n(S) 1326 221
