Problema Solution
The incidence of occupational disease in an industry is such that the workers have a 20% chance of suffering from it. What is the probability that out of six workers 4 or more will contract the disease?

Binomial Problem with n = 6 ; p(suffer od) = 0.20 ; p(do not suffer od) = 0.8
od= occupational disease
P(4<= x <=6) = 1 - binomcdf(6,0.2,3) = 0.0170
