Jamal and his friend are playing a game. In each round, they randomly hold up between 1 and 5 fingers, inclusive. For Jamal to win, the sum and the product of the number of fingers must be even. His friend wins all other rounds.

What is the probability that Jamal wins a round?

After a few rounds, Jamal decides not to choose randomly, but only to hold up either 2 or 4 fingers. What is the probability that he wins now?

paula, cory, and krista

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

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.
