Question 5 (14.28 points)
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

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) =

non - happening is  q

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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
