Classic Probability
If the Probability of an event happening is 70%, what are the ODDS of the event happening?
7:10
07:3
10:7
3:7

Answer 1

b) 7 : 3

That is the odds of the event happening is 70 percent and not happening is 30 percent.

Explanation:

Probability:-

In a random experiment, let there be n mutually exclusive and equally likely elementary events. Let E be an event of the experiment. If m is the favorable events ( that is happening event) and n be the exhaustive events (total no of cases) then the probability is defined as

P(E) =
`(m)/(n)`

non - happening is q
`= 1-p`

the total probability is equal to one that is

(p +q =1)

given data the event happening is 70 percentage and non - happening is remaining 30 percentage.

p = 70 and q =30

the odds of the event happening in ratio is 70:30

that is 7:3
