Answer:
b) 7 : 3
That is the odds of the event happening is 70 percent and not happening is 30 percent.
Step-by-step 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) = [tex]\frac{m}{n}[/tex]
non - happening is q [tex]= 1-p[/tex]
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
