Problem Solvers
of the Fortnight 

In our last problem of
the fortnight for the year we noted that each U.S. $1 bill contains an 8digit
string between two letters as a serial number. For example, E12345678A
might be such a serial number. Suppose that the two letters of the
serial number are given, say E at the beginning and A at the end. Under
the assumption that every 8digit string is equally likely to occur between
the E and the A, what is the probability that a serial number contains five
or more of the same digit?
