Find the probability that 0, 1, or 2 people are unemployed.
At least 3 means, 3-8 unemployed.
Once you have the probability of 0-2 unemployed you can subtract from 1 to find the value for 3-8 of the 8 unemployed.
P%280%29=1%2A%280.87%29%5E8%280.13%29%5E0=0.3282
P%281%29=7%2A%280.87%29%5E7%280.13%29%5E1=0.3923
P%282%29=21%2A%280.87%29%5E6%280.13%29%5E2=0.2052
So for 0,1,and 2, the probability is
P=0.3282%2B0.3923%2B0.2052=0.9258
Now we can subtract to find the answer we want,
For 3-8 inclusive, highlight%28P=1-0.9258=0.0742%29
