I think what you're looking for is this: http://en.wikipedia.org/wiki/Checking_wh...robability
If you want 99% level of confidence (Z=2.5759, E=0.01) that you've arrived at the true probability, you'll need data for at least 10617 trials.
So go out there and buy 10617 EE and 10617 equips. Record how many passes and fails and you'll ascertain the probability with +-1% maximum error.
