Question

three cards are drawn randomly from a pack of 52 cards. what is the probability that one will be black and two red?

Answer 1

"Let us consider A to be the required event.

There are 4 kings in a pack of 52 cards - Heart king,

club king, diamond king & Spade king.

So, possible pairs of kings= 4P2 = 4 *3 = 12.

Possible combinations = n(A) =12 * 50

P(A) = n(A)/n(S) = 12*50/52*51*50 = 1/13 * 17= 1/221
