If it is 10% that one rapist did not leave DNA, then for three it has to be .1% or 1 in 1000!!
The 10% number seems really high if no condom was used and she was assaulted orally.
Actually it is
.1 x .1 x .1 = .001
oops, same thing.
I was thinking probabilities.

It's been one stop after another for freed inmate Alan Newton, who was released from prison last week after 22 years in jail for a crime he did not commit.
After a week of parties, picnics and public appearances, Newton, a former bank teller from the Bronx, is adjusting to life on the outside after DNA testing cleared him in the vicious rape and beating of a Bronx woman whose shaky identification sent him away for nearly half his life.
DNA from Newton that was compared to a sperm sample recovered as evidence after the rape showed conclusively that Newton had nothing to do with the brutal attack.

So why was this guy freed when the NYT tells us:
"Outside experts say it is possible for a rapist to leave no DNA evidence."
Amazing isn't it? She claims she was assaulted in three orifices by men not wearing any protection and no DNA is left.
