7/21=1/3

Step-by-step explanation:

In order to solve this we first have to calculate the total of the possible outcomes when withdrawing a tshirt from the drawer and we do that by adding all of the shirts:

8+6+7=21

And to calculate the probability of getting a white shirt from the drawer we divide the number of deisred outcomes by the total number of outcomes, since there are 7 white shirts, we divide that by 21, and reduce:

7/21

1/3

So there is 1/3 chance you get a white shirt when pulling a random shirt from the drawer.

For x greater than 36 inches, the perimeter of the picture frame is greater than 156 inches.

Step-by-step explanation:

If the width of the picture frame is x inches,

The length of the same is (x + 6) inches

Therefore, the perimeter of the picture frame is 2[(x + 6) + x] =4x + 12 inches

Therefore, for the perimeter to be greater than 156 inches,

4x + 12 > 156

=> 4x > (156 - 12)

=> 4x > 144

=> x > 36
