The employees of a subsidiary that does asbestos cleanup are being tested forindications of asbestos in their lungs. The firm is asked to send four employees whohave positive indications of asbestos on to a medical center for further testing.Suppose 40% of the employees have asbestos in their lungs. Let Xi be the number ofemployees who are screen-tested to find one who has positive indications of asbestosin his/her lungs.a. Let Y be the total number of employees tested to find four with positive asbestos intheir lungs. Define Y as a function of X. Using the MGF technique, find the probabilitydistribution of Y.b. Concerned with the cost of screening test; Lee Hu Kay would like to know themaximum number of employees tested to find one who has positive indications ofasbestos in his/her lungs (Z). Given X₁, X₂, X₂ and X4, derive the distribution function ofZ.c. Suppose the cost of each screening test is 5000 pesos. Let W be the total costincurred by the company to find one employee who has positive indications ofasbestos in his/her lungs. Find the distribution function of W using the CDF technique.

A big concert was held at the Bowl. Men and women had to go through separate lines to enter. The turnstile on the female entrance showed a total count of 1595 females, but the males turnstile was broken. A sample was taken from the 200 seats in section A, which showed 74 males in the section. Use the male count from section A to estimate the total number of people attending the concert. (Assume none of the seats were empty.)
Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country.
