if the probability that an event will occur is 9/10 what are the odds in favor of the event occurring

The odds in favor of an event occurring can be determined by taking the probability of the event occurring (9/10) and dividing it by the probability of the event not occurring (1 - 9/10 = 1/10).

Therefore, the odds in favor of the event occurring are (9/10) / (1/10) = 9/1.

This can also be expressed as 9:1.

To determine the odds in favor of an event occurring, you need to find the ratio of the probability that the event will occur to the probability that it will not occur.

Given that the probability of an event occurring is 9/10, the probability of it not occurring can be calculated as:

1 - 9/10 = 1/10

So, the ratio of the probability of the event occurring to the probability of it not occurring is:

(9/10) / (1/10)
= (9/10) * (10/1)
= 9/1

Therefore, the odds in favor of the event occurring are 9 to 1.
