Question 1185311
.
A local county has an unemployment rate of 8%. A random sample of 19 employable people are picked at random 
from the county and are asked if they are employed. Find the probability that exactly 5 in the sample are unemployed. 
(The distribution is a binomial. Round your answers to 4 decimal places.)

<pre>
It is the binomial type probability distribution.


The number of trials n= 19; the probability of the success trial is  0.08,  and the number of success trials k = 5. 


    P = {{{C[19]^5*0.08^5*(1-0.08)^(19-5)}}} = {{{11628*0.08^5*0.92^14}}} = 0.011857 = 0.0119 (rounded).     <U>ANSWER</U>
