Line l and line m are straight lines. Line l and m intersect with a third line to form 5 angles. From top left, clockwise, the angles are b, 90 degrees, c, 124 degrees, a.
Which statements are true regarding the angles in the figure? Select two options.
Measure of angle a = measure of angle b
Measure of angle a = measure of angle c
Measure of angle a + measure of angle b = measure of angle c
Measure of angle a + measure of angle b = 90 degrees
Measure of angle a + measure of angle b + measure of angle c = 124 degrees

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.)
