Suppose a life insurance company sells a $200000 one-year term life insurance policy to a 21-year-old female for $230. The probability that the female survives the year is 0.999554. Compute and interpret the expected value of this policy to the insurance company.

$ 229.80

Step-by-step explanation:

The expected value would be the subtraction between the value that she originally paid for the probability that she can live that year and the value of the insurance (subtracting what she paid) for the probability that she will lose her life.

Value of the insurance policy: $ 230

Value in case of death: $ 200,000 - $ 230 = $ 199,770

Probability of living: 0.999554

Probability of dying: 1 - 0.999554 = 0.000446

Replacing we have:

$ 230 * 0.999554 - $ 199,770 * 0.000446

= $ 229.80

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
