Problem:

A particular species of fish is known to weigh more than 10 pounds with probability .01. Suppose that 10 such fish are caught and weighed. Show that the probability that the total weight of the 10 fish is above 100 lbs is at most .1.

Attempt:

It seems obvious that .01 x 10 = 100, but I'm not sure how to relate this fact to the probability that it being the case is .1. Any ideas?
