Let S be the sample space. Then, n(S) = ₂c⁵² = (52 x 51)/(2 x 1)= 1326. (2 x 1) Let E = event of getting 2 kings out of 4. ∴ n(E) = ₂c⁴ = (4 x 3)/(2 x 1) = 6. ∴ P(E) = n(E)/n(S) = 6/1326 = 1/221.
From a pack of 52 cards, two cards are drawn together at random. What is the probability of both the cards being kings?
