What are all the possible 11 digit combinations of letters a through z and numbers 0-9 mixed together?

There are 26 letters plus 10 digits making 36 characters in all.
Using the mathematical definition of "combination" whereby 11 of those 36 characters are chosen to be a group so the order of selection does not matter:
36C11 = 36!/(36-11)!11!
= 36!/25!11!
= 600,805,296 combinations
If you meant the mathematical "permutations" where the order of the 11 selected characters does matter:
36P11 = 36!/(36-11)!
= 36!/25!
= 23,982,224,839,372,800 permutations
Finally if you are referring to how many strings of 11 of those characters could be chosen (eg for a password) where any of the characters could be repeated, then there are:
3611 = 131,621,703,842,267,136 possible words.
No way are all of any of those going to be listed (by me, or anyone else - unless they really have loads of time on their hands) as there are at least six hundred million, eight hundred and five thousand, two hundred and ninety six sets of 11 characters to write out (plus spaces between them).

What are the possible combinations of a 3 digit lock for numbers 0 through 39?
Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.

What are all the possible 11 digit combinations of letters A-Z and numbers 0-9 combined?
We can use 36 characters for each of the slots in the combination. Therefore, we have 36^11 possible combinations, or 131,621,703,842,267,136 combinations.

What are the possible different combinations of numbers in four digits?
If the numbers contain zeros, the total number of combinations is 10,000. You can work this out easily logically: For ten single-digit numbers (0,1,2,3,4,5,6,7,8,9) then there are 10 possible 'combinations' For numbers with 2 digits then for each possible digit in the 10s column (e.g. in the 20s range) there are another 10 possible combinations (20,21,22,23,24,25,26,27, 28,29). As there are 10 possible ranges (single digits, teens, twenties, thirties etc) there will be 10 X 10 or 100 possible combinations. using the same logic, for three digits, there will be 10 X 10 X 10 or 1000 digits. And for 4 digits there will be 10 x 10 x 10 x 10 = 10,000 possible combinations. So for a number, say, with x digits, the total number of combinations of those digits will be 10 x 10 x 10..... etc with x numbers of 10s in the calculation. You can find out the number of combinations of any set of letters or numbers in the same way. as an example, to find out, say, the possible combinations of letters in the alphabet of 26 letters, then using the same method this can be given as 26 x 26 x 26 x 26............. with 26 '26's' in a row multiplied together. This gives the staggering amount of approximately 615612 followed by 31 zeros.
How many possible combinations could be constructed using 3 letters and 3 numbers for a license plate?
26x26x26x10x10x10 = 17,576,000
How many possible unique alpha numeric combinations are there using all letters for 4 characters?
im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.
How many possible combinations are there of 9 numbers from 20 drawn numbers?
There are 167960 combinations.
How many combinations are there for a license plate that has 3 numbers from 0 -9 and 2 letters from A-Z?
Using the extended fundamental counting principle, you multiply the total number of options in each space together. There are 10 possible numbers for each of the three number spots, so you would do 10x10x10=1,000. Multiply this by 26 and 26 again for all the possible letters that can go in each letter spot: 1,000x26x26=676,000 So you have 676,000 possible license plate combinations.
How many possible alpha numeric combinations using letters and numbers for 4 characters?
26 lower case letters + 26 uppercase letters + 10 numerals = 62 characters 624 = 14776336
How many possible combinations of six numbers are possible from six numbers?
Just 1.
How many different combinations can be made from a combination of 3 letters and 3 nuimbers?
Taking this bit by bit... For each number there are 10 possibilities so three numbers has 10^3 which is 1000 for each letter there are 26 choices, so for three letters you have 26^3 which is 17576 together there are 17576 * 1000 options which makes 17576000 possible combinations of letters and numbers and I suspect that is what you want. However if the order of the combination is important you must take into account the position of each letter/number and remove duplicate combinations. Good luck with that
