For high school students, college admissions to the nation's most selective universities is very competitive. For example, it was reported in 2007 that elite school A accepted about 12% (.12) of its applicants, and elite school B accepted 18% (.18). Joanna has applied to both schools. Assuming that she is a typical applicant, she figures that her chances of getting into both A and B must be about 2.16% (.0216).
