To find the odds ratio in favor of an event occurring, we divide the probability of the event occurring by the probability of the event not occurring.

In this case, the probability of the event occurring is 0.20. The probability of the event not occurring is 1 - 0.20 = 0.80.

So, the odds ratio in favor of the event occurring is:

0.20 / 0.80 = 1/4

This can also be written as 1 to 4, meaning that for every one time the event occurs, it will not occur four times. Therefore, the correct answer is A) 1 to 4.
