If condoms are 98% effective and if the pill is 99% effective, what effectiveness would you have if you used both?

>> No.10478190

100% since you'll probably not reproduce. But if by accident your pickle gets stuck in a rubber and inadvertently slides into a pussy it'll be 97.02% effective.

P(pill effective) = .99
P (condom effective) = .98
P(A union B) = P(A) + P(B) - P(A intersect B)
= .99 + .98 - (.99)(.98)
= .9998

Condoms suck and are ancient and the pill is costly overtime unless it you also use it for acne control (really wish there is male equivalent). IUD's are underrated cost less overtime, covered by insurance and lost a long while.

The pill is only relevant when the condom fails. The chance of both failing is 0.02*0.01. Thus the answer is 1-0.02*0.01 = 99.98%

Assuming independent probabilities, the effectiveness is 1 - 0.02*0.01 = 0.9998

But part of that condom failure rate comes from being an idiot, which isn't independent from the pill failure rate.

You take on two levels of rejection this way so it would fractal into the posterior and engage for a scheduling of the front that some surface tension may arise as a medium rather than afford the costs of value as like weight versus the effect of friction between two skin shells and the weighted variances between them. It's a certainty of weight that one will rip and here we are expecting both to but only one will rip and the other should be severing. It's a pundit scheme.

I say 98% to both.

dont the condom companies use a wierd interpretation of "99% effective"? like if you have sex 500 times, there's a 1% chance one of those times the giro will be pregnant.

>> No.10482479

>>10478314
98% probably.
Condoms are usually ineffective because of improper usage, not because they have inherent flaws.
Adding more things to screw up isn't likely to do any better.
