You can put this solution on YOUR website! In a survey of 300 students,53% reported a profession close to their major.
If 9 of those survey subjects are randomly selected without replacement for follow up survey, what is the probability that 3 of them entered a profession closely related to their major?
-----
Binomial Problem with n = 9 and p = 0.53
---
p(x=3) = 9C3(0.53)^3*(0.47)^6 = binompdf(9,0.53,3) = 0.1348
