Question

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

Answer 1

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

n(S) = 52 

Number of red cards (hearts + diamonds) = 26

E = event of drawing a red card 

n(E) = 26 

Probability of drawing a red card = `(n(E))/(n(S)) = 26/52 = 1/2`
