With 6 different letters, no repetition (like you have 6 different Scrabble tiles), and if order is important, then the proper statistical term is permutation, rather than combination, but many people refer to this type of application as a combination.
The permutation (no repetition) of n items taken rat a time is n!/(n-r)! with in this case n=6 and r=6. The exclamation mark is notation for factorial.
6! = 6 * 5 * 4 * 3 * 2 * 1. (6-6)! = 0! which is defined as 0! = 1
So we have 6 * 5 * 4 * 3 * 2 * 1 = 720 different possibilities.

How could you find the number of different combinations of six letters in a computer password?
When trying to work out how many different combinations there are, you need to know how many options there are for each value. If the password only contains lower case letters, then we have 26 options for each value. For each letter in the password, there are 26 options, so the total number of possible options is 26x26x26x26x26x26 or 266 This equals 308,915,776 so there are 308,915,776 possible different combinations of six letters.

Suppose you roll two dice Find the probability of rolling a sum of 6?
Find the possible combinations of rolling a six with two dice: 1 + 5 = 6 5 + 1 = 6 2 + 4 = 6 4 + 2 = 6 3 + 3 = 6 3 + 3 = 6 Six in total. Find the number of possible combinations; Number of Sides on the Dice (6) to power of how many dice (2) = 36 Number of Times the Dice will sum to Six (6 times) -------------------------------------------------- Number of Possible outcomes This will give us 6 out of 36 rolls. Or reduced 1/6 rolls
