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 odds in favour of an event A are 2 : 5. Find P(A) and P vec A .

What do you mean by statistical independence of events?

The odds against a certain event are 5 to 2, and the odds in favour of another event independent of the former are 6 to 5. Find the chance that one at least of the events will happen.

The odds in favour of an event are 3:4 . Find the probability of : occurrence

If the probability of the occurrence of a certain event E is 3/11, find (i) the odds in favour of its occurrence, and (ii) the odds against its occurrence.

The odds against an event are 5 to 2 and the odds in favour of another disjoint event are 3 to 5. Then the probability that one atleast of the event will happen is
