- 100/e = 37 (approx.). This is sometimes known as the "secretary problem".
- It is Example 8.16 in _Probability and Measure_ by Billingsley. I won't
- write the solution here, since it is a page of computations. The general
- topic that includes problems like this is "optimal stopping". The classic
- text on the subject is _Great Expectations_ by Chow, Robbins, & Siegmund.
