Ex 14.2, 2 A coin is tossed twice, what is the probability that at least one tail occurs? When 2 coins are tossed , Sample Space = S = {HH, HT, TH , HT} n(S) = 4 Let A be the event that at least 1 tail occurs Hence A = {HT, TH, TT} n(A) = 3 P (A) = Number of outcomes favourable to ATotal number of possible outcomes = n(A)n(s) = 𝟑𝟒
