6.165 Stalked College Women. In the article “Violence against Women: How Safe Are Our Institutions of Higher Learning?” (Family & Intimate Partner Violence Quarterly, Vol. 05, No. 04, pp. 341–349), researcher D. Thomas asserts that the population of students attending colleges and universities, and women in particular, are at higher risk of being victims of sexual assault than are their non–college-bound peers. According to research, 13% of college women have been stalked. If 100 college women are selected at random, what is the probability that the number who have been stalked is

1. a. less than 10?
2. b. between 15 and 20, inclusive?
3. c. at least 15?
