Question: this is a math 1139 permutation and combinations (probability) they are going to choose 8 people. specifically, 3 will be chosen randomly out of 19 people who work in office b, and 2 will be chosen randomly out of 12 people who work in office c. i myself work in office a. how many different groups of 8 are possible under those conditions, and also how many groups are possible with me in them, and the probability that i would be in the group that gets to go?

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
