There are 30 fish in a pond. We know that 13 of these fish are males, 4 of these males are salmon, and there are 8 salmon in the pond. What is the probability that a randomly chosen fish is a salmon, given that it is a male?
-------------------------------------------
P(salmon | male) = P(salmon and male)/P(male)
= (4/30)/(13/30) = 4/13
