A home security has a reliability rate of 99%. In a sample of nine homes equipped with this system who
\n" ); document.write( "experienced an attempted burglary, what is the probability that eight or more than eight alarms were triggered,
\n" ); document.write( "----
\n" ); document.write( "Binomial Problem with n = 9 and p(triggered) = 0.99
\n" ); document.write( "------
\n" ); document.write( "P(8<= x <=9) = 1 - P(0<= x <=7) = 1 - binomcdf(9,0.99,7) = 0.9966
