Question

The odds for an event are 5:7. Find the probability of the event.

Answer 1

Answer:

70%

Step-by-step explanation:

7 times 14 is 98, which is the closest 7 can get to 100. So 5 times 14 is 70. And 70 represents that 70% is the probability of 5:7.

Answer 2

Answer:

7/12

Step-by-step explanation:

Concept= Probability

Given= The odds for an event.

To find= The probability of event occurring.

Explanation=

We have been given that the odds for an event are 5:7. Find the probability of the event.

Here the information says about the odd of happening it.

This means that event would not occur and the first number of ratio is the probability of not happening.

So the odd of event are 5:7. The sum of ratio is 5+7=12.

Therefore the chance of event not occurring which is odd of an event is 5/12.

So now we know if 5/12 is the probability of event not occurring therefore for the event to occur the probability is 7/12 according to the information provided.

To cross check this , we know event not occurring probability is 5/12. So the event to occur probability is 1-5/12

=> (12-5)/12

=> 7/12

Therefore it is clear that probability of event occurring is 7/12.
