(a) What would be the expected value for the number of right-handed people in the group?

(b) What is the probability that exactly 5 of the people in the group are right-handed?

(c) What is the probability that at least 5 of the people in the group are right-handed?

(b) Use a binomial probability table. Values are: n = 7, x = 5, and p = .88

(c) Use the table again. Find x = 5,6,7. Use same values for n and p. Add together for total probability.

I hope this will help get you started.
