Answer: 0.375
Step-by-step explanation:
Let x be the event that at exactly 2 heads occurs
Let s be the sample space
Therefore;
n(s) = 8
n(x) = 3 (HHH, HHT, THH)
p(x) = n(x)/n(s)
p(x) = 3/8
p(x) = 0.375
Answer:
The answer is the third option, (-2,1)
The question is phrased a little weird, but I wanna say inferences.
The volume of a cone is such that
, where r is the radius and h is the height.
Recall that the diameter is twice the radius. So given that the diameter is 8 ft, the radius must be 4 ft. The height is given as 5 ft.
Plugging into the formula, you have
