Hi, I'm reading a paper about stats in psychology (https://www.ejwagenmakers.com/2007/pValueProblems.pdf) and there is an equation in there that I cannot work out.

I'm not a mathematician, but as I understand, the binomial coefficient could be simpified as such:

1000! / 500!(1000!- 500!)

Then, I'd multiply the outcome of that by 0.5^1000. According to the paper (p781), the end result should be "about .025"

However, I'm having difficulty with the initial step because 1000! and 500! give infinite numbers. Is there a simple way of calculating the whole equation to get 0.025?

Many thanks!
