Ex15.1, 23 A game consists of tossing a one rupee coin 3 times and noting its outcome each time. Hanif 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. Possible outcomes = (H, H, H), (H, H, T), (H, T, H), (T, H, H), (T, T, H), (T, H, T), (H, T, T), (T, T, T) Total possible outcomes = 8 Number of outcomes where Hanif loses the game = 8 – 2 = 6 P (Hanif will lose the game) = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ π‘œπ‘’π‘‘π‘π‘œπ‘šπ‘’π‘  π‘€β„Žπ‘’π‘Ÿπ‘’ π»π‘Žπ‘›π‘–π‘“ π‘™π‘œπ‘ π‘’π‘ )/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘œπ‘’π‘‘π‘π‘œπ‘šπ‘’π‘ ) = 6/8 = 3/4
