<PRE><B>Question 185795</B>
If 10% of the people who are given a certain drug experience dizziness, find these probabilities for a sample of 15 people who take the drug.
-----------
There are all binomial problems:
-------------- 
a. At least two people will become dizzy.
Ans: 1 - binomcdf(15,0.1,1) = 0.4510
-------------------------------
b. Exactly three people will become dizzy.
Ans: binompdf(15,0.1,3)= 0.1285
-------------------------------
c. At most four people will become dizzy.
Ans: binomcdf(15,0.1,4) = 0.9873
