Topic: Binomial Distribution

The binomial distribution doesn't work. Am I writing it the wrong way?

For example:
fact(4)/[fact(x)*fact(4-x)]*[[(0.64^x)*[(1-0.64)^(4-x)]]

with n = 4
and p= 0.64

Thanks for help

Re: Binomial Distribution

Your problem is that the fact function is only defined for integers. You can force Graph to calculate for integers by setting Draw type to Dots and specifying a range. I have attached a file that show this.
