&lt;pre&gt;&lt;b&gt;
Binomial, n=10 trials, probability of 1 success in 1 trial = p=15% = 0.15,

What is the probability of r=8 successes

nCx*p&lt;sup&gt;r&lt;/sup&gt;(1-p)&lt;sup&gt;n-r&lt;/sup&gt;

10C8*(0.15)&lt;sup&gt;8&lt;/sup&gt;(1-0.15)&lt;sup&gt;10-8&lt;/sup&gt;

10C8*(0.15)&lt;sup&gt;8&lt;/sup&gt;(0.85)&lt;sup&gt;2&lt;/sup&gt;
