The odds in favour of an event are 3:5 find the probability of occurrence of this event?

If the odds in favour of an event are 7 :1, then the probability of occurrence is

If the odds in favour of an event are 9:4 , then its probability of occurrence is

If the odds in favour of an event are 7:3, then its probability of occurrence is -

If the odds in favour of an event are 9:4 , then its probability of occurrence is -

If the odds against an event are 4:5, then the probability of occurrence of the event is0

If the odds against an event are 4 : 5, then the probability of occurrence of the events is -

The odds in favour of an event A are 3:4 the odds against another independent event B are 7:4 what is the probability that at least one of the event will happen?

The odds in favour of an event are 4:3 . The odds against another independent event are 2:3 . What is the probability that at least one of the events will occur ?

The probability of occurrence of at least one event of two events X and Y is 0.6.-If the probability of occurrence both is 0.2, find P(barX) + P(barY)

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) denotes the probability of occurrence of the event T , then (a) P(E)=4/5,P(F)=3/5 (b) P(E)=1/5,P(F)=2/5 (c) P(E)=2/5,P(F)=1/5 (d) P(E)=3/5,P(F)=4/5
