Step-by-step explanation:
Each sheet of plywood measures
.
We have to cover the surface of the house, minus the surface of the hole of the stairs.

To know how many sheets will be needed, we divide the surface to be covered by the surface of each sheet

Answer:
y: 139 x: 139 too
Step-by-step explanation:
Total number of possible outcomes = 36
Total number of outcomes with a sum of 12 = 1
{6,6)
Total number of outcomes with a sum of 3 = 2
{1,2}{2,1}
P(12 first, then 3) = (1/36)(2/36) = 1/648
Answer: The probability is 1/648
