Question

A card is drawn from a well-shuffled pack of 52 cards. Find the probability that the card drawn is a red or a king.

Answer 1

Number of possible outcomes when card is drawn from pack of 52 cards = 52 

n(S) = 52 

E = event of drawing a red or a king

= 26 red cards (13h + 13D) + 2 black kings  ...[Since 26 red cards contain 2 red kings] 

n(E) = 28 

Probability of drawing a red or a king = `(n(E))/(n(S)) = 28/52 = 7/13`
