Question 667998
In testing a new drug, researchers found that 4% of all patients using it will have a mild side effect. A random sample of 13 patients using the drug is selected. Find the probability that exactly two will have this mild side effect.
---------
Binomial Problem with n = 13 ; p(effect) = 0.04 ; p(none) = 0.96
-----
P(x = 2) = 13C2*(0.04)^2*0.96^11 = binompdf(13,0.04,2) = 0.0797
