Find the binomial probability P(x = 6), where n = 15 and p = 0.50. Solution Let\'s say you have n=15. The outcome is either x or y for any given n with a probability than any given outcome is x of 0.50. What is the probability that the total number of x\'s is exactly 6. Order does not matter. Use the formula from wikipedia: http://en.wikipedia.org/wiki/Binomial_probability n=15, k=6, p=0.5 (15!/(6!(15- 6)!))*(0.5^6)*((1-0.5)^(15-6)) = 0.152740479.

1. Find the binomial probability P(x = 6), where n = 15 and p = 0.50.
Solution
Let's say you have n=15. The outcome is either x or y for any given n with a
probability than any given outcome is x of 0.50. What is the probability that the total number of
x's is exactly 6. Order does not matter. Use the formula from wikipedia:
http://en.wikipedia.org/wiki/Binomial_probability n=15, k=6, p=0.5 (15!/(6!(15-
6)!))*(0.5^6)*((1-0.5)^(15-6)) = 0.152740479
