Suppose an employer will hire one new employee from
a group of n candidates interviewed in a random order,
according to the algorithm HIRE-NEW-ASSISTANT as
shown below. As they are interviewed in succession, a
decision is made for each whether to hire or not. A
necessary (but not sufficient) condition for deciding to
hire a candidate is that the candidate must be better
than all previous candidates who were interviewed but
not hired. Suppose candidate ci is hired. What is the
probability that it was the best of all n candidates? HIRE

=1 to n Interview candidate ck If candidate ck is better
than candidates c1 ... ck-1 With 50% chance Hire
