V=0.95h^2.9
h=7.5 feet→V=0.95(7.5)^2.9
V=0.95(344.8876664)
V=327.6432830
Rounded to the nearest tenth:
V=327.6 cubic feet
This is a combinations problem.
The total number of possible 2-item combinations is (1000 choose 2)
The number of 2-defective combinations is (300 choose 2)
The probability =
32x+64 = 160
32x = 96
x = 3
The answer is 8.4 all you do is divide them together to get your answer.
