If miranda flips a coin twice, what is the probability that both coins will land heads up? the probability that the first coin will land heads up is 1/8, 1/4, 1/2, 3/4? . the probability that the second coin will land heads up is 1/8, 1/4, 1/2, 3/4. the probability that both coins will land heads up is 1/8, 1/4, 1/2, 3/4?

The probability that both coins will land heads up is 1/4. The probabilty the first coin will land heads up is 1/2. The probability that the second coin will land heads up is 1/2.

Step-by-step explanation:

Each coin only has 2 options for what it can land on and each option is equally likely so its 1/2. To find the chance that both will land heads up multiply (1/2) by (1/2) to get 1/4.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
