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

math: is this done correctly 
PsyDAG,
There are only 4 male salmon in the pond = 4/30
