A home security system is designed to be triggered in 96% of attempted burglaries.
If 9 homes equipped with such a system experience an attempted burglary, find the probability that at least 8 alarms are triggered. Round your answer to four decimal places
----------
P(8<=x<=9) = 1 - binomcdf(9,0.96,7) = 0.9522
