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
