how many combinations are there in the alphabet?
9556
Since letters can be in any combination or permutation as long as they arent words as your question suggests, any letter can occur in any of the 3 slots thus the answer is simply number of letters in the alphabet to the power of 3, also commonly known as “cubed”. Thus, 26 x 26 x 26 or 26^3 which is 17576.

If we assume your letters range from A to Z and your digits from 0 to 9, you have 26 possibilities per letter and 10 per digit. This gives you 26^4*10^4 which is roughly 4 billion and a half.

There are about 1,000 combinations possible for a 3-digit number/code. There are 10,000 combinations possible for a 4-digit number/code.

Answer and Explanation: The number of combinations possible with 5 letters is 65,780. The combination formula in mathematics is as follows: {eq}_{n}C_{r}=\frac{n!}{

For the first four moves of chess alone, there are 318,979,564,000 (source: http://EzineArticles.com/1717732 ) different combinations.

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N. Now, this assumes that you count 00000 or 00534 as "5-digit numbers".

There are 60 of them. Using the same argument as above there are 60 60 = 3600 two "digit" combinations and 60 60 60 = 216000 three "digit" combinations.

With respect to that technical meaning, there is only one combination of the four numbers 4, 5, 8, and 7, taken four at a time: All four of them. There are 24 combinations. 4578, 4587, 4758, 4785, 4857, 4875, 5478, 5487, 5748, 5784, 5847, 5874, 7458, 7485, 7548, 7584, 7845, 7854, 8457, 8475, 8547, 8574, 8745, and 8754.

Since there are 26 letters and 10 digits you have a total of 36 characters to choose from for each position. Starting from the left you can fill in the first position in 36 possible ways. For each of the 36 possibilities for the first character there are 36 possibilities for the second character.

The number of possible combinations that are possible with 26 letters, with no repetition, is 67,108,863.
1137280
The total number of combinations is then: 26 x 26 x 26 x 10 x 10 x 10 = 17,576,000 ≈ 18 million.

List all combinations of the letters ABCD in groups of 3. There are only four combinations (ABC, ABD, ACD, and BCD). Listed below each of those combinations are the six permutations that are equivalent as combinations.

There are 1 billion 9 digit numbers (000,000,000 through 999,999,999). There are 45 different combinations of two different numerals (10 x 9 divided by 2). There are 512 (2 to the 9th power) different permutations for any two numbers to be used in a 9 digit number. 45 x 512 = 23,040 - 10 = 23,030.

Alphabet. The French alphabet is based on the 26 letters of the Latin alphabet, uppercase and lowercase, with five diacritics and two orthographic ligatures. The letters ⟨w⟩ and ⟨k⟩ are rarely used except in loanwords and regional words.

So there are possible numbers of length 4. It's easy. The first digit can be 1,2,3,4,5 or 6 (6 combinations). We choose the second,third and fourth digit the same way we did it with the first (so it's 6*6*6 combinations) and the final answer is 6*6*6*6=1296 combinations.

There are only four combinations (ABC, ABD, ACD, and BCD). Listed below each of those combinations are the six permutations that are equivalent as combinations. We learned in the last section that combinations were symmetric.
