My gf claims that her IUD is 99.95 percent effective.

She said that if I release inside her 10,000 times that she'd have like a 50% chance because the 99.95 percent would stack up like

0.05, 0.10, 0.15 ect.

I told her that's retarded and that's like saying oh I didn't get 21 red on roulette I have a greater chance this time.

She did 'Liberal arts and sciences and a statistics unit'

Like the 99.95 percent chance is always against itself, but she didn't listen. I'm only a simple electrician and I'm not smart enough to explain how she's wrong but I know she is.

Please help me prove men are smarter /sci/ thanks
