Question 969846: To determine the number of trout in a lake, a conservationist catches 94 trout, tags them and throws them back into the lake. Later, 44 trout are caught; 11 of them are tagged. How many trout would the conservationist expect to be in the lake?
Answer by Boreal(15235) About Me  (Show Source):
You can put this solution on YOUR website!
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.
