You roll a fair 6-sided die 8 times. what is the probability that you will roll at least four "4's"?

p(four) = 1/6, n = 8

P(x ≥ 4) = 1 - binomcdf(8, 1/6, 3) = 1 - .9693 = .0307

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
