What is the P (A) if we know that the odds in favor of A occurring are 3 to 4?

To determine the probability (P) of an event A occurring, given the odds in favor of A occurring, you can use the following formula:

P(A) = Odds in Favor of A / (Odds in Favor of A + 1)

In this case, the odds in favor of A occurring are 3 to 4. To calculate the probability, plug the values into the formula:

P(A) = 3 / (3 + 4) = 3/7

Hence, the probability of event A occurring is 3/7.
