I am very strong in math except for in 1 area and that's probabilities. Is there anyone who can please check my answers for me and tell me if I am close or way off base? Thanks in advance!
- Ten percent of adults say oatmeal raisin is their favorite cookie. You randomly select 12 adults and ask each to name his or her favorite cookie.
- The two major criteria for a binomial probability experiment are independence and two possible outcomes. Explain how this experiment meets each these two criteria.
Every answer will either be a success (they like oatmeal raisin cookies) or a failure (they donít like oatmeal raisin cookies). For independence, the probability of success remains constant for the entire experiment because the answer will either be oatmeal raisin or something else.
- What is the value of :
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)
d. What is the probability that 3 or less adults will say oatmeal raisin is their favorite cookie?
(You may use the table)
0.282+0.377+0.230+0.085 = 0.974
