Question 1184907
.
<pre>

It is the binomial type probability distribution problem.


The number of trials n= 10; the probability of the success trial is  30% = 0.3,  and the number of success trials k = 8. 


    P = {{{C[10]^8*0.3^8*(1-0.3)^2}}} = {{{((10*9)/(1*2))*0.3^8*0.7^2}}} = 0.001447 (rounded) = 0.1447%.     <U>ANSWER</U>
