You can put this solution on YOUR website! In a small town, 60% of the households have dogs. If 5 households are randomly selected, what is the probability that at least 4 of them have dogs?
-----
Binomial Problem with n = 5 and p(have dog) = 0.6
-----
P(4<= x <=6) = 1 - P(0<= x <=3) = 1 - binomcdf(5,0.6,3) = 0.3370
