Question 1140838: As of March 2018, the unemployment rate is 4.1, which means that there is a 4.1 % probability that
a working age adult is unemployed.
7. If we surveyed 100 adults, what is the probability that exactly 5 of them are unemployed?
8. What is the probability that no more than 2 are unemployed?

for exactly 5, it is 100C5*0.041^5*0.959^95=0.1635
for no more than 2 unemployed look at 0,1,2
for 0 it is 0.959^100=0.0152
for 1 it is 100C1*0.041*0.959^99=0.0650
for 2 it is 100C2*0.041^2*0.959^98=0.1375
That probability is the sum, or 0.2177
