the probability of a house will be burglarized is = 5% which is = .05
the probability of a house will NOT be burglarized is = (1 - .05)
the probability of a second house will NOT be burglarized is =
(1-.05)*(1-.05)= (1-.05)^2
the probability of a third house will NOT be burglarized is=
(1-.05)*(1-.05)(1-.05)= (1-.05)^3
so, the probability of NONE = (1-.05)^10 = .598736939 = .5987
