Assume a system has 5 subsystems. As long as 3 of the subsystems are operational, the system is working. Also assume that each subsystem has a probability of survival equals to 0.9 for 1000 hours of operation without any failure.
\n" ); document.write( "What is the probability that the system will survive a 1000 hours of operation without a loss of more than 2 subsystems.
\n" ); document.write( "----
\n" ); document.write( "Binomial Problem with n = 5, p(fail) = 0.1, p(not fail) = 0.9
\n" ); document.write( "----------------------
\n" ); document.write( "Comment: That condition means you could have zero, one, or two subsystems fail.
\n" ); document.write( "P(0<= x <=2) = binomcdf(5,0.1,2) = 0.9914
