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?

I think they are just asking about salmon and trying to confuse me with adding more to the question.

There are 8 salmon. My answer is 8/30 or 4/15

There are only 4 male salmon in the pond = 4/30

To calculate the probability that a randomly chosen fish is a salmon given that it is a male, you need to use conditional probability. Conditional probability is calculated by dividing the probability of the intersection of two events by the probability of the first event.

In this case, the first event is choosing a male fish, and the second event is choosing a salmon. We know that there are 13 male fish out of the total 30 fish in the pond. So, the probability of choosing a male fish is 13/30.

Out of the 13 males, we also know that 4 are salmon. So, the probability of choosing a salmon given that it is a male is 4/13.

Therefore, the probability that a randomly chosen fish is a salmon, given that it is a male, is 4/13.
