Mark and rene have a 1: 00pm tee time to play golf today. there is a 0.8 probability that mark will make it. there is a 0.5 probability that rene will make the tee time. if mark makes the tee time, then there is a 0.8 chance that rene will then make the tee time. what is the probability that rene will make the tee time but mark will not?

the answer is c. 23/3

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
