from this question "let no one enter who does not know mathematics".

:
:
mathematics; 5distinct consonants, appear 7 times.
one answer: 7/11.

Answer 2

let = 2/3
no = 1/2
one = 1/3
enter = 3/5
who = 2/3
does = 2/4 = 1/2
not = 2/3
know = 3/4
mathematics = 7/11

I suppose if you wanted th whole thing: 23/38
Note that's not the average per word, which is :
(2/3 + 1/2 + 1/3 + 3/5 + 2/3 + 1/2 + 2/3 + 3/4 + 7/11) /9 =
(7/3 + 2/2 + 3/5 + 3/4 + 7/11) / 9 = 0.591
