According to the police sources a car with a certain protection system will be recovered 85% if the time. Find the probability that 5 out of 7 stolen cars will be recovered.
--------
Binomial Problem with n = 7 and p(recover) = 0.85
----
P(x = 5) = 7C5*(0.85)^5*(0.15)^2 = binompdf(7,0.85,5) = 0.2097
