Question 630463: I am having a difficult time with this problem.
With 71.1% of a town's population made up of college students, what is the probability that in a random sample of 150 people from the town, more than 50 are not college students?

You can put this solution on YOUR website! With 71.1% of a town's population made up of college students, what is the probability that in a random sample of 150 people from the town, more than 50 are not college students?
-----
Binomial Problem withe n = 150 and P(not college) = 0.289
---
P(x > 50) = 1 - binomcdf(150,0.289,49) = 0.1345
