Question 969846
One quarter of the trout caught were tagged.  We infer that the number of trout in the lake is 4 times the number of tagged trout there were originally.

4*94=376 trout.

this is the expected value.  

Check, and you catch about 12% of them (44/376)
12% of 94 tagged would be 11.28 tagged, or 11.
