If the odds in fovour of an event be 3 : 5, then the probability of non-occurrence of the event is

If the odds against an event be 2 : 3, then the probability of its occurrence is

If the odds against an event be 2 : 3, then the probability of its occurrence is

The odds in favour of the occurrence of an event are 3:5 . Find the probability of the non-occurrence of the event.

For any event A

An event has odds in favour 4 : 5, then the probability that event occurs, is

Let E and F be two independent events. The probability that exactly one of them occurs is 11/25 and the probability if none of them occurring is 2/25. If P(T) deontes the probability of occurrence of the event T , then
