Thread: 100000 women

Nope. That is only when a birth control pill is used.

Yes, that's the premise.
To put it in clearer points, there's not much point in doing a 99.99% certainty pregnancy test if you're also using a 99.99% contraceptive, because a positive result only gives you 50% certainty that you're actually pregnant, instead of the advertised 99.99%.

Of course, that's assuming that pregancy rate without contraceptive is 100%, which it isn't.

The entire test begins with the premise that both of the tests are 99.99% effective

50% of the .01% of the people who used the pregnancy test will be pregnant
