(d)Let the probability that C wins = x Then, probability that B wins = 2x and probability that A wins = 4x Then, sum of all probability for an event to happen is equal to 1 x + 2x + 4x = 1 7x = 1 ⇒ x =
1
7
∴ Probability that C wins = 1/7 Similarly, probability that A wins = 4/7 Now, the probability that A loses = 1 -
