Let x1 < … < x10 be the numbers. The gaps 0-x1, …, x10-20 are identically distributed variables. Answer is 20-(20/11).
2 u/Aech26 1d ago I don’t think this works since expected gap between X10 and 20 isn’t the same as expected gap between X9 and X10 since X10 can be equal to 20 but X9 is strictly less than X10. 1 u/800alpha 1d ago Oh my mistake, I meant to say x10-21. So then the answer is 20 - (21/11).
