**Mary**, Monday, April 26, 2010 at 10:45pmI think I remember a bit of this from when we were generating OC curves for a math modeling project last semester.

In my notes there is the equation:

P(d)= (n!/(d!(n-d)!))*(p^d)(1-p)^(n-d)

It's assumed that the total lot is very large, so when you take n, the sample size, out doesn't change the remainder.

P(d)= prop of observing exactly d

number of defectives= d

random sample= n

p= fraction of defectives per lot.

Hope this helps
