DNA testing probabilities go something like this ....
we found say 5 markers that match the defendant and the sample. (I picked a small number to make the example shorter)
each of those has the following probabilities of occuring in a random person :

1) 1 in 1000
2) 1 in 10
3) 1 in 10000
4) 1 in 7
5) 1 in 100

so we multiply all those together and get a probability of mismatch of : 1 in 7,000,000,000

I even told a guy at the state crimelab that was stupid - not that he cared.

If you can't learn to do it well, learn to enjoy doing it badly.
