The Graduate Management Admission Test (GMAT) website provides information about the undergraduate majors of those who took the test in specific years. Suppose that in a certain year: 51% majored in business or commerce; 18% majored in engineering; 17% majored in the social sciences; 7% majored in the sciences; 4% majored in the humanities; and 3% listed some major other than the preceding. Assume there are no double majors.
