Question 449984
The unemployment rate in a city is 15%. Find the probability that at most 1 out of 8 people from this city sampled at random are unemployed. Round your answer to four decimal places. 
---
1/8 = 0.125
----
z(0.125) = (0.125-0.15)/sqrt(0.15*0.85) = -0.0700
---
P(x <= 0.125) = P(z< -0.07) = 0.4721
