so the probability of not drawing a white ball 50 times in succession is .99^50. 1-(.99^50) is 39.4993...%
try 1/100 + 1/99 + ... >> ...+ 1/52 + 1/51. ~69%. and s/t else. it reaches 100% at abt 37 left (63 pulls). or 1/ln e. eulers #.
math hasta come to u. u cant go gettit. ppl like einstein & squawking tried to bend it to how they wanted it. doesnt work. and if u cant figure out s/t as simple as black ball-white ball then u dont have it. iows dont be a meggy.
The discussion was about drawing with replacement. Your original post was vague on that point.
Interesting that you think you're certain to have pulled the white ball when there are still 37 left in the bag if you do it without replacement. You might want to check that.
I agree with your last sentiment.
(Btw wouldn't it be simpler to just write 1 rather than 1/ln e?)
...when i wanna run a quick check w/ say less than 1000 samples i use excel. and function out say the 'randarray' w/ its arguments. tests out every time. for this one i also strung in the 'unique' operative (ridding ea black ball along the way). i ran it like 10x's and it tada'ed...goodbye.
