Question 574576
A machine has 9 identical components which function independently. The probability that a component will fail is 0.2. The machine will stop working if more than three components fail. Find the probability that the machine will be working. 
-------
Binomial Problem with n = 9 and p(fail) = 0.02
---
P(0<= x <=3) = binomcdf(9,0.02,3) = 0.9993
