comment How do I explain the number e to a ten year old?
Well, no sorry of course you can also define 1/e as the limit of the probability you quote. I think it would still make for a mysterious explanation though.

This is the beautiful problem of derangements en.wikipedia.org/wiki/Derangement I can't see an answer to the OP's question here either (proving that you get 1/e requires the definition of e :) ).

I think this is best known as the secretary problem: en.wikipedia.org/wiki/Secretary_problem I frankly can't see an answer to the OP's question though.

I agree with Dennis Serre. What do you mean by 'good'? Do you have a simple example or heuristic?

comment Epsilon regularity: what does it say and where does it come from?
Many thanks for this answer! I still haven't digested it properly, but I understand the critical trick. I will probably ask for details soon as I still find it difficult to see what's happening geometrically.

It'd be funny if your collaborators now left a comment here saying 'please do'. :)
