प्रश्न
A card is drawn from a well-shuffled pack of 52 cards. Find the probability that the card drawn is 5 of heart or diamond.
उत्तर
Number of possible outcomes when card is drawn from pack of 52 cards = 52
n(S) = 52
E = event of drawing a 5 of heart or of diamond = {5H, 5D}
n(E) = 2
Probability of drawing a 5 of heart or of diamond = `(n(E))/(n(S)) = 2/52 = 1/26`
