Since any two letters of the alphabet do not duplicate each other, then the number of arrangements of any two letters is the same as the number of permutations of 26 things taken 2 at a time. That is 26! / (26 - 2)!, or 26! / 24!, or (26) (25), or 650.
The first letter can be any one of the 6 letters. For each of those . . .The second letter can be any one of the remaining 5 letters. For each of those . . .The third letter can be any one of the remaining 4 letters. For each of those . . .The fourth letter can be any one of the remaining 3 letters. For each of those . . .The fifth letter can be any one of the remaining 2 letters.The total number of different ways they can be arranged is (6 x 5 x 4 x 3 x 2) = 720 .
11!/(2!2!2!)=11!/6=6652800 [It would be 11! if all of the letters were different, but you divide by two for each of the three letters which appear twice: m,a,t.]
There are 26 letters (A-Z) that can be chosen for the first character, for each of which there is a choice of 10 digits (0-9) for the second character. → number of outcomes = 26 x 10 = 260.
