At utopia university, 510 students took the college literacy observation disk (clod) pilot test to identify any literacy traits that could be noticed. here are the results for graduates and undergraduates.
fail pass total
graduates 55 125 180
undergraduates 50 280 330
totals 105 405 510
1. for a randomly selected student, determine the following probabilities and round to 2 decimal
points:
a. p(pass) = __%_
b. p(pass and graduate) = [assume mutually exclusive (independent) events]
c. p(fail/undergraduate) =
d. p(graduate/fail) =
e. p(pass or undergraduate) =

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

i believe the correct answer is b.

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.
