probability = number of favorable events / total number of events
as we all know alphabets = 26
the letters in the mathematics = 11
there are some repeated letters in the word = 3

∴the number of favorable events = 11-3 
                                                    =   8
probability = 8/26 
                 = 4/13
∴ the probability = 4/13
