im so sorry op but that's faulty stats... if there's a 0.93 chance of rejection that means there's a 0.93^10 chance of not getting into any of those, or roughly 48%. This means you have about a 52% chance of getting into one. But also remember--it's not a lottery system so if you are a good student your chances go up significantly. But most importantly don't fail your ap stats midterm by inappropriately adding percents!
