प्रश्न
A card is drawn from a pack of 52 cards. Find the probability that the card drawn is a queen or a jack.
उत्तर
Number of possible outcomes when card is drawn from pack of 52 cards = 52
n(S) = 52
E = event of drawing a jack or a queen = {JH, JS, JD, JC, QH, QS, QD, QC}
n(E) = 8
Probability of drawing a jack or a queen = `(n(E))/(n(S)) = 8/52 = 2/13`
