there are 36 different combination possibilities. Try them all.
Here are some examples:CPJzwsuRpNZgUPbziSLePcyE
Starting with three different letters, six two-letter combinations can be made, if the order of the two letters is important. Only three combinations can be made if the order of the two letters is not important. Example: ABC AB AC BA BC CA CB - six variations But if (for your purposes) BA is the same as AB, Then there are only three: AB AC BC

It is called an alphanumeric password.
There are 26 letters in the alphabet.If letters may be repeated in the airport code, then there are (26 x 26 x 26) = 17,576 possibilities.If adjacent letters can't be duplicates, then there are (26 x 25 x 25) = 16,250 possibilities.If all three letters must be different, then there are (26 x 25 x 24) = 15,600 possibilities.
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.

There are 26 different letters that can be chosen for each letter. There are 10 different numbers that can be chosen for each number. Since each of the numbers/digits that can be chosen for each of the six "spots" are independent events, we can multiply these combinations using the multiplicative rule of probability.combinations = (# of different digits) * (# of different digits) * (# of different digits) * (# of different letters) * (# of different letters) * (# of different letters) = 10 * 10 * 10 * 26 * 26 * 26 = 103 * 263 = 1000 * 17576 = 17,576,000 different combinations.
36! / 8!(36-8)! = 36! / 8!28! = 36x35x34x33x32x31x30x29x28 / 8x7x6x5x4x3x2x1 Cancel down as appropriate 6x17x11x31x30x29x28 = 847289520 possibilities That is 847,289,520. In words, Eight hundred and forty seven million,two hundred and eighty nine thousand,five hundred and twenty.
The password is different for each person. You have to find your own three letters.

The security question - is something only the legitimate user should know the answer to ! The safest password to use should be at least 10 digits (letters and/or numbers) long. There are 3,656,158,440,062,976 possible combinations for a 10-digit password using letters and/or numbers !
No is a word. On is a word.
The number of combinations of 6 letters is 6! or 720.
