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 don’t 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.*
i.n? __________

*12_*___________

ii.p? __________

*0.1*____________

iii.q? _________

*0.9_*____________

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)

*0.085*
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*
