All possible outcomes for flipping a coin three times are listed below: (H = heads up, T = tails up)
{HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}

What is the probability of obtaining at least 2 tails?
Select one:

1/8

7/8

3/8

1/2

he answer is x=1x3 because x=1 to x=3

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

your answer is  

d.

196.5 m2

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
