Question

To determine the number of trout in a​ lake, a conservationist catches 94 ​trout, tags them and throws them back into the lake.​ Later, 30 trout are​ caught; 10 of them are tagged. How many trout would the conservationist expect to be in the​ lake?

Answer 1

Tagged? 84 if the 10 weren’t thrown back in general? 94+20=114 I’m not sure if this answers your question, sorry if it doesn’t, your question wasn’t very specific.
