A TV remote control has keys for channels 0 through 9.
a) If a key is selected at random, what is the probability that the key for channel 8 is pressed?
b) If a key is selected at random, what is the probability that the key for an even number is pressed?
c) If a key is selected at random, what is the probability that the key for a number more than 6 is pressed?

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.
