Hi There,
Sorry for this silly question, but I'm unable to remind my old mathematics rules...
I would like to know for a population of let's say 10000 parts that includes 5 defect parts.
If a sample of 125 is taken, what is the probability to get the 5 defect parts in the sampling?
I guess it start like that: 5/10000 x 4/9999 X 3/9998 X 2/9997 X 1/9996...
but I can't remember how to compute the 125 samples around?
Thanks
