The Transportation Security Administration (TSA) is responsible for airport safety. On some flights, TSA officers randomly select passengers for an extra security check prior to boarding. One such flight had 36 passengers—12 in first class and 24 in economy class. Some passengers were suspicious when all 10 passengers chosen for screening were seated in economy class. What is the probability that all 10 passengers chosen would be in economy class? Part (a) Number of ways to choose 10 economy passengers out of 24 =

Part (b) Total number of ways to choose 10 passengers out of 36 =

Part (c) What is the P(All 10 passengers economy) =

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.
