A 28 year-old man pays $243 for a one-year life insurance policy with coverage of $100,000. If the probability that he will live through the year is 0.9993, what is the 28 year-old man's expected value for the insurance policy?

  -$173

Step-by-step explanation:

The expected value is the sum of products of payments and their respective probabilities.

  He pays $243 with probability 1: (-$243)(1) = -$243

  He receives $100,000 with probability 1 -0.9993: ($100,000)(0.0007) = $70

The expected value for the man is ...

  -$243 +70 = -$173  . . . .  a cost of $173

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
