Question 240765
): according to goverment data, the probability that an adult was never married is 15%, in a random survey of 10 adults, what is the probability that at least
8 were married?
------------------
This is a binomial problem with n=10, p = 0.15, 8<=x<=10
-------------------------------
Ans: P(8<= x <=10) = 1 - binomcdf(10,0.15,7)
= 0.0000086651...
