प्रश्न
A card is drawn from a pack of 52 cards. Find the probability that the card drawn is a black ace.
उत्तर
Number of possible outcomes when card is drawn from pack of 52 cards = 52
n(S) = 52
Number of black ace cards = 2
E = event of drawing an ace
n(E) = 2
Probability of drawing a black ace = `(n(E))/(n(S)) = 2/52 = 1/26`
