If you flip three fair coins, what is the probability that you'll get all three heads?

1/8

Step-by-step explanation:

The probability that you will get heads on any coin flip is 1/2, meaning half of the time you will get heads. The probability of this happening to you twice in a row is 1/2*1/2, as you have a probability of 1/2 of getting heads on each flip. This means the probability of getting three heads in a row is 1/2*1/2*1/2=1/8

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
