Question 618547: Suppose we want to determine the (binomial) probability(p) of getting 5 heads in 11 flips of a 2-sided coin. Using the Binomial Probabilities Table in Appendix B of the text, what values of n, x and p would we use to look up this probability, and what would be the probability?

You can put this solution on YOUR website!
n = 11
x = 5
p = 1/2

You can either use an appendix or calculator to evaluate



which should yield P(x=5) = 231/1024 = .22559
