Question

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.

Answer 1

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`
