Question 283905
A poll found that 23% of the workers at the company live outside city limits. If 4 workers are selected at random, what is the probability that at least one worker lives outside city limits?
--------------------------------------
P(student lives outside) = 0.23

P(student lines inside) = 0.77
----------------------------------
Your Problem:
P(at least one of 4 lives outside) = 1 - P(all 4 live inside)
= 1 - 0.77^4
= 0.6485
==================
