Question

A card is drawn from a pack of 52 cards. Find the probability that the card drawn is not a club.

Answer 1

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

n(S) = 52 

Number of club cards = 13

E = event of drawing a club card 

n(E) = 13  

Probability of drawing a club card = `(n(E))/(n(S)) = 13/52 = 1/4` 

Probability of not drawing a club card = `1 - 1/4 = (4 - 1)/4 = 3/4`
