5.In a swimming competition, only 3 students A, B and C are taking part. Theprobability of A's winning or the probability of B’s winning is three times theprobability of C's winning. The probability of the event either B or C to win is4) 7

Three students A,B,C are to take part in a swimming competition. The probabilities of A's winning or the probability of B's winning is 3 times the probability of C's winning. The probability of the event of either B or C to win is

Three students A, B and C are to take part in a swimming competition. The probability of A's winning or B's winning each is 3 times the probability of C's winning. The probability of C 's winning if there is no tie is . (A) 4/7 (B) 3/7 (C) 2/7 (D) 1/7

Two horses A and B run a race. If the probability of A's win is twice the B then the probability of B's win is

In a competition A, B and C are participants. The probability that A wins is twice the probability of B, the probability that B wins is twice that of C. The probability that A loses is

In a competition A, B and C are participating. The probability that A wins is twice that of B, the probability that B wins is twice that of C. find the probability that A losses.

In a competition A, B and C are participating. The probability that A wins is twice that of B, the probability that B wins is twice that of C. find the probability that A losses.

In a competition A, B and C are participating . The probability that A wins is twice that of B, the probability that B wins is twice that of C. Then the probability that A loses is

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that both win

If the probability of a horse A winning a race is 1/4 and the probability of a horse B winning the same race is 1/5, then the probability that either of them will win the race is

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that none of them wins
