You flip a fair coin 8 times in a row. What is the probability that it will land on tails every single time? Write the answer as a fraction.

50/100 chance

Step-by-step explanation:

It would be a 50/50 chance, because the coin has two sides, so it's a 50/50 chance that it'll land on tails all 8 times.

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.
