Question

From a well-shuffled pack of 52 cards, a card is drawn at random. Find the probability of it being either a red king or a black queen.

Answer 1

n(S) = 52

No. of Red cards = 26,

Red king cards = 2

No. of Black cards = 26,

Black queen cards = 2

No. of red king cards = n(K) = 2

∴ The probability of being either a red king or a black queen = \(\frac{1}{13}\)
