Question

a game consists of tossing a one rupee coin 3 times and noting its outcome each time wins if all the tosses give the same result i.e. three heads or three tails and loses otherwise. Calculate the probability that Hanif will lose the game​

Answer 1

Total Outcomes = 8

(H,H,H)  (H,H,T)  (H,T,H)  (H,T,T)  (T,H,T)  (T,H,H)  (T,T,H)  (T,T,T)

Outcomes that will help Hanif to win the game = (H,H,H)  (T,T,T)  =  2

Probability to win the game = 2 / 8 = 1 / 4 = 0.25

Probability to lose the game = 1 - 0.25 = 0.75
