In dictionary words are listed alphabetically, so to find the words
Listed before $E$ should start with letter either $A,\;B, \;C \;or \;D$
But the word $EXAMINATION$ doesn`t have $B,\;C \;or \;D$
Hence the words should start with letter $A$
The remaining $10\;places$ are to be filled by the remaining letters of the word $EXAMINATION$ which are $E,\; X,\; A,\; M,\; 2N, \;T,\; 2I, \;0$
Since the letters are repeating the formula used would be
Where $n$ is remaining number of letters \[{{p}_{1}}and\text{ }{{p}_{2}}\] are number of times the repeated terms occurs.
The number of words in the list before the word starting with $E$
\[=\text{ }words\text{ }starting\text{ }with\text{ }letter\text{ }A\text{ }=\text{ }907200\]
