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