I've already mentioned the forumula. It goes like this: For condoms, there is a 98/100 (98%) chance you will not get pregnant.
So if you have sex twice: 98/100 * 98/100 = 9604/10000 = 96.04%. So there is a 96.04% chance you will not be pregnant if you have sex twice.
100 - 96.04 = 3.96% chance you are pregnant by the time you've down it twice.
Trust me, Math and Biology (yes, they teach this in Bio. as well) are my strong subjects :x

It doesn't work that way. Your formula doesn't take into account all the confounding variables. It's not correct. For any given episode of sexual intercourse, the chance of prophylactic failure resulting in pregnancy is 6-26%%. It remainsas suchfor each time that you have sex.
Integrity of the condom, timing of menstrual cycle, appropriateness of prophylactic application, adequacy of birth control usage, and other variables must be taken into account, which is why there is such a wide range.
The chances of a woman getting pregnant on birth control even with perfect usage are almost alwaysnear 1/100 depending on the type of OCP andcompliance.
Obviously, I never doubted that, there are even more variables such as genetics, diet etc. but I never doubted that. I was just trying to prove that birth control pills are more safer than condoms, especially in the long run where the difference is almost crucial.Birth control pills are NEVER safter than condoms. No matter how much math you do. Working through percents tells you nothing about the likelihood of acquiring disease or the likelihood that she will have an adverse reaction to the hormones now running through her body.
Going on birth control simply because you don't want to use a condom is a foolish idea. OCPs should be used in women that don't desire pregancy and want to continue to use another form of birth control, as well, like condoms.
