How many combinations does a 3 digit alphanumeric have?
(26+10)3=46656.
There are 504 different 3-digit numbers which can be formed from numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 if no repetition is allowed. Note: We can also use the multiplication principle to answer this question.
If letters can be repeated as many times as you want, there are 6 options (A, B, C, D, E, or F) for the first letter, second letter, and third letter. Then 63=216 are the number of options for all three-letter-words.
Alphanumeric = 26 lowercase letters and 10 numbers, so there are 36 choices for each character. Since there are 6 characters, and each character has the same number of choices, there are in total 366=36×36×36×36×36×36 possibilities, which is roughly 2.177⋅109.
1 Answer. 7770 triples of distinct alphanumeric characters.
We get that there are 15,600 possible 3-letter passwords, with no letters repeating, that can be made with the letters a through z.
How many different combinations can you make with the numbers 1234? So there are {1,2,3,4} these 4 numbers. So there are 64 total ways.
Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! = 3*2*1 = 6 ways.
How many 3 letter words are there in English? The Official Scrabble Player's Dictionary, Volume 6, lists 1,065 three-letter words.

How do you find out how many combinations are there?
The number of combinations of n objects taken r at a time is determined by the following formula: C(n,r)=n! (n−r)!
An alphanumeric example are the characters a, H, 0, 5 and k. These characters are contrasted to non-alphanumeric ones, which are anything other than letters and numbers. Examples of non-alphanumeric numbers include &, $, @, -, %, *, and empty space.
Therefore, in 1000 arrangements 3 digits can be formed from the digits 0 through 9.
So the number of 3-number combinations are- (1,2,3),(1,2,4),(1,3,4),(2,3,4). Each can be arranged in 6 ways, so we get 24 ways totally.
(ii) repetition of the digits is not allowed? Solution: Answer: 60.
∴ Total number of 3-digit numbers = 3×4×5=60. Q.
If you pick any letter ( m, a, t, or h ) for the first "letter slot" in the word, there are four different choices. Then, for the next "slot", you have three other letters to choose from to put in there, so that triples the combinations. That's already 4⋅3 possible ways, or 12 .
How many different arrangements are there of 3 letters chosen from the word combination? - Quora. How many different arrangements are there of 3 letters chosen from the word combination? C(8,3) + 3 C(7,1) = 77.

For each of the 362 ways to fill in the first two characters there are 36 ways to fill in the third character. Hence there are 363 ways to fill in the first three characters. Continuing in this fashion you can see that there are 366 = 2 176 782 336 ways to fill in all 6 characters.
Possible combinations for 5-digit numbers: 9*10^4=90000. The first digit must be 1 to 9; i. e. with the exclusion of 0, otherwise the resulting number would not be a 5-digit one. The first number is 10000; the last one: 99999.
By comparison, this 3-dial lock (three wheels, each with digits 0-9) has 10 × 10 × 10 = 1, 000 possible combinations. The total number of combinations is not very different, but the Simplex Lock is much harder to pick because it is harder to systematically test each possible combination.
1234, 1243, 1423, 4123, 1324, 1342, 1432, 4132, 3124, 3142, 3412, 4312, 2134, 2143, 2413, 4213, 2314, 2341, 2431, 4231, 3214, 3241, 3421, 4321.
Typing (alphanumeric) keys.
These keys include the same letter, number, punctuation, and symbol keys found on a traditional typewriter.

Alphanumeric characters: alphabetic characters A through Z. numeric characters 0 through 9.
There are 4 * 3 * 2 = 24 combinations if repetition is not allowed. If repetition is allowed, there are 4 * 4 * 4 = 64 combinations.
The third letter can also be any one of 26, leading to 26 * 26 (or 26 ^ 2) combinations for each vowel. The total number of 3-letter combinations is then 5 * 26 * 26 = 3,380 combinations.
How many possible combinations of 3 items from a group of 5 are possible?
So 5 choose 3 = 10 possible combinations.
10*10*10=1000. total 456796*10000= 456796000 combinations.
So, 60 different combinations of 3 letters out of 5 given letters can be formed.
Thus, there are 512 possible three-digit combinations.
Take a 3-letter palindromic word: The first letter has 26 options, as well as the second letter. The last letter must be the same as the first letter, so that only has one option. 26 x 26 x 1 = 676, which is a palindrome itself!
