You can put this solution on YOUR website! According to the government 5.3% of those employed are multiple job holders. In a random sample of 150 people who are employed, what is the probability that fewer than 10 hold multiple jobs? What is the probability that more than 50 are not mulriple job holders.

Binomial Problem with n=150 and p= 0.053
---
What is the probability that fewer than 10 hold multiple jobs?
P(0 <= x <10) = binomcdf(150,0.053,9) = 0.7264
-------------
What is the probability that more than 50 are NOT multiple job holders.
P(51 <= x <=150) = 1- binomcdf(150,0.947,50) is practically 100%
