To calculate an average, add up all of your numbers, and then divide by the number of numbers. In this case, add all the numbers in the tagged column and then divide by 10. Then add all the numbers in the not tagged column and divide by 10.

Can't work the other part since you didn't share an estimate of the number of fish in the lake.
