Show all work 1. pb (there is a line on top) is a line segment on a number line. it has endpoints at -2 and 12. what is the coordinate of its midpoint? 2. the midpoint of cd (there is a line on top) is e(-1, 0). one endpoint is c(5,2). what are the coordinates of the other endpoint? 3. explain the distance formula. then use it to calculate the distance between a(1, 1) and b(7, -7).

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.)
