Question 350153
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(0)=1*(0.87)^8(0.13)^0=0.3282}}}
{{{P(1)=7*(0.87)^7(0.13)^1=0.3923}}}
{{{P(2)=21*(0.87)^6(0.13)^2=0.2052}}}
So for 0,1,and 2, the probability is
{{{P=0.3282+0.3923+0.2052=0.9258}}}
Now we can subtract to find the answer we want,
For 3-8 inclusive, {{{highlight(P=1-0.9258=0.0742)}}}
