Suppose that a certain candidate is running in a city election.
A recent poll of 500 randomly chosen voters concludes that 60% of the voters prefer this candidate.
Determine the probability that the candidate will get less than 56% of the votes.
-----
Binomial Problem: n = 500 ; p = 0.6
---
Note 56% of 500 = 280
------------
P(0< x < 280) = binomcdf(500,0.6,280) = 0.0380
