Question

PROBABILITY PROBLEM NEED HELP ASAP (attached below)

Answer 1

Multiply each probability by each number of hours.

Answer 2

The idea is this: Given 10 days, what is the expected number of days each person will study for? Then assuming they study for exactly that number of days, on average how many hours in total will they have studied for? The "average hours of studying" tells you how many hours they will study for, for each day. Does that make sense?

Answer 3
