HOW TO WIN THE RACE ?

The chance of winning the race of the horse A is 1/5 and that of horse B is 1/6. What is the probability that the race will be won by A or B ?

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 that A can win a race is 3/8 and the probability that B can win it is 1/6 . If both run a race, find the probability that one of them will win the race, assuming that both cannot win together.

The probability of a horse A winning a race is (1)/(4) and that of a horse B winning the same race is (1)/(3) . Considering that winning is matually exclusive, find the probability that (i) Either of them win (ii) None of them win

In a 2 km race A wins over B by 200 m or 20 seconds. B can give a startup 500 m to C in 2 km race. Find out by how much time A will win over C?

A race course is 400 metres long. A and B run a race and A wins by 5 metres. B and C run over the same course and B wins by 4 metres. C and D run over it and D wins by 16 metres. If A and D run over it, then who would win and by how much ?

In a horse -race, the probabilities to win the race for three horses A,B and C are 1/4,1/5 and 1/6 respectively. Find the probability to win the race of any one horse.
