if I had a vase of 1000 balls, and I keep randomly sampling 10 balls at a time, what's the expected time until I see all of the balls?
@SuricrasiaOnline I don't think you can say "expected time", there's always a chance you'll never see all of them, however small
@noiob @SuricrasiaOnline that would be unexpected, i think
@confusedcharlot @SuricrasiaOnline well I don't think that's how maths works. You could say "after x time there's a 90% chance you've seen every ball"
@confusedcharlot @noiob for expected time it's the integral of the PDF*time. for some probability distributions it is undefined but for many it has a value
@SuricrasiaOnline @confusedcharlot that makes a lot more sense than what I was thinking
@noiob @confusedcharlot probability distribution function
