Pitney Bowes surveyed 302 directors and vice presidents of marketing at large and midsized U.S. companies to determine what they believe is the best vehicle for educating decision makers on complex issues in selling products and services. The highest percentage of companies chose direct mail/catalogs, followed by direct sales/sales rep. Direct mail/catalogs was selected by 38% of the companies. None of the companies selected both direct mail/catalogs and direct sales/sales rep. Suppose also that 41% selected neither direct mail/catalogs nor direct sales/sales rep. If one of these companies is selected randomly and their top marketing person interviewed about this matter, determine the following probabilities:

a. The marketing person selected direct mail/catalogs and did not select direct sales/sales rep.

b. The marketing person selected direct sales/sales rep.

c. The marketing person selected direct sales/sales rep given that the person selected direct mail/catalogs.

d. The marketing person did not select direct mail/catalogs given that the person did not select direct sales/sales rep.
