If 70% of all women are employed outside the home, find the probability that in a sample of 50 women at least 7 are not employed outside the home
--------
Binomial Problem with n = 50 and p(employed outside) = 0.7 ; p(not emp) = 0.3
----------
P(7<= x <=50) = 1-P(0<= x <=6) = 1 - binomcdf(50,0.3,6) = 0.9975
