What is the difference between X and ncx?
“x” is the number of heads in our example “p” is the probability of getting a head, which is 50% (or .5) “q” is the probability of not getting a head (which is also .5). q = 1 – p. “nCx” is the number of ways we can “choose” x from n. This is called a “combination”.

How do you calculate NCX?
Formula: nCx = n! / (n - x)! x! To calculate a value for nCx you use the formula given on the top left of pg. 204 in the text, which is n! / (n - x)! x! In other words, you calculate the factorial for n, and then divide that by the product of the factorials for n-x and x.
