Question
A card is drawn from a pack of 52 cards. Find the probability that the card drawn is a black card.
Solution
Number of possible outcomes when card is drawn from pack of 52 cards = 52
n(S) = 52
Number of black cards (spade + clubs) = 26 = E
n(E) = 26
Probability of drawing a black card = `(n(E))/(n(S)) = 26/52 = 1/2`
