Question 564215: In 2006, the General Social Survey asked respondents whether they favored or opposed sex education in public schools. According to the survey results, 89% favored sex education in public schools. If two of the respondents are randomly selected, what is the probability that at least one favors sex education in public schools?
How do I solve this problem?
Thank you. Colleen

-----
Binomial Problem with n = 2 and p(favor) = 0.89 ; P(not favor) = 0.11
---
P(1<= x <=2)
= 1 - P(x = 0)
= 1 - (0.11)^2
= 0.9879
