Question 684732: Suppose we want to determine the (binomial) probability(p) of getting 6 heads in 15 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! Suppose we want to determine the (binomial) probability(p) of getting 6 heads in 15 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?
------
n = 15
p = 1/2
x = 6
----
P(x = 6) = 15C6(1/2)^6*(1/2)^9 = 15C6/2^15 = 5005/32768 = 0.1527
