> If you use condoms perfectly every single time you have sex, they’re 98% effective at preventing pregnancy. But people aren’t perfect, so in real life condoms are about 85% effective — that means about 15 out of 100 people who use condoms as their only birth control method will get pregnant each year.

Why don't we consider the combined probability of condoms + birth control (heck, even + vasectomy, etc.)? It would seem a lot more reasonable to me to take that as a more appropriate measure of real-world risk.
