The odds in favour of the occurrence of an event are 8 : 13 . Find the probability that the event will occur.

Write the formula for calculating the probability of occurance of an event.

If the probability of occurance of an event is 0.6, then find the probability of its non-occurance.

If odds against an event be 5 : 6, find the probability of occurence of this event.

Probability of occurring of an event always lies between _____.
