Parallel processing that uses two or more computers working together to solve a single problem using parallel processing two computers can solve a problem in 20 minutes so that's a together amount together is 20 minutes if working alone one computer can solve a problem in nine minutes less than the time needed by the second computer. How long will it take the faster computer working alone to solve the problem?

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.)
