Bob and Gabe are racing to see who can get his community service hours for scouting completed first. Bob, who has already completed 100 hours, plans to volunteer for 2 hours
per week going forward. Gabe hasn't started yet, but plans to dedicate 4 hours per week to his volunteer hours. How many hours will each boy have volunteered by then?
his volunteer project from now on. Before too long, the boys will be tied, with the same
number of volunteer hours. How many hours will each boy have volunteered by then?

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
