Question 317044
Ten percent of adults say oatmeal raisin is their fav cookie. You randomly select 12 adults and ask each to name his or her fav cookie. 
1. what is value of N?, p?, q?
---
N = 12 ; p = 0.10 ; q = 0.90
-------------------------------------- 
c. What is the probability that exactly 3 of the 12 adults surveyed will say their favorite cookie is oatmeal raisin? (You may use the table)
P(x=3) = 10C3*(0.1)^3*(0.9)^7 = 0852
--------------------------------------------------- 
d. What is the probability that 3 or less adults will say oatmeal raisin is their favorite cookie?
P(0>= x >=3) = binomcdf(12,0.1,3) = 0.9744
