Given that the letter “O” occurs exactly 5040 times and the letter “U” occurs exactly 5040 times, and assuming a relationship where N(E) / N(O) = 9/4 (or N(E) / N(U) = 9/4, which implies N(O)=N(U) as given), we can calculate the frequency of E.
N(E) = N(O) * (9/4)
N(E) = 5040 * (9/4)
N(E) = (5040 / 4) * 9
N(E) = 1260 * 9
N(E) = 11340.
