Question

If the odd against the occurence of an event be 4:7 find the proabilty of the occurence of the event.

Answer 1

`Probability = (7)/(11)`

Explanation:

Given

`Odds:Occurence = 4:7`

Required

Determine the probability of the occurrence

First, we need to get the total of the ratio

`Total = 4 + 7`

`Total = 11`

Next, is to calculate the required probability as follows;

`Probability = (Occurrence)/(Total)`

`Probability = (7)/(11)`

Hence, the required probability is

`Probability = (7)/(11)`
