Point Z is the incenter of ΔWXY. Point Z is the incenter of triangle W X Y. Lines are drawn from point Z to the sides of the triangle to form line segments Z B, Z C, and Z A.
Which statements are true? Check all that apply.

m∠ZYX = m∠ZXY
ZX bisects ∠WXY
BZ = WZ
The circle inscribed in ΔWXY will have a center at point Z.
Point Z is equidistant from the sides of ΔWXY.

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.)
