Higher order thinking jack is growing red wiggler worms
to make compost. he measured the lengths of two
young worms. the 10-day old worm is 19 inch long. the
20-day old worm is 1 inches long. about how much longer
is the 20-day old worm than the 10-day old worm? explain
how you found your estimate.

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.)
