That depends - on how many letters are in the password - AND - if any letter can be repeated. For example... an eight-digit password has 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 = 208,827,064,576 possible combinations IF every letter can b repeated. If each letter can only be used once, then the formula is 26 x 25 x 24 x 23 x 22 x 21 x 20 x19 = 62,990,928,000 possible combinations.

How do you write the alphabet in chines?

There is no alphabet per se, in Chinese. Chinese characters each represent an entire syllable. In mainland China, there is some use of the Western Alphabet for phonetic spelling, while in Taiwan, there is a syllabary for phonetic "spelling". Often referred to as "bo-po-mo-fo" the way we call our alphabet the ABCs, this syllabary has symbols to represent the beginnings of syllables and symbols to represent the ends of syllables. Still not an alphabet, though: in the above examble,"bo" is one symbol, "mo" is another, etc. These are "initials", symbols representing the beginnings of syllables. "Finals", symbols for the ends of syllables, represent sounds such as "an" and "ung", etc. Clear as mud? :D


Do apostrophes used to show plurals of numbers and letters?

If you want. I've heard that an apostrophe with letters in numbers is an American thing. I've also heard that the Brits do it differently. I'm American and I don't use an apostrophe with letters and number as long as there is no confusion to the reader.Examples:1300s or 1300'sABCs or ABC'sBoth examples are correct. It is my opinion that there is little chance of the reader becoming confused.Examples when lack of an apostrophe might confuse the reader:Mind your p's and q's.Always remember to dot your i's and cross your t's.Answer 2:Apostrophes are commonly, but erroneously, used in numbers such as calendar decades or centuries instead of using the correct form, e.g. 1800s or the 1970s. According to the Oxford Dictionary, numbers used in this format should not have an apostrophe. It is acceptable (though not a rule) to use it for individual numbers such as "count in 7's as far as 100". Though acceptable, it is unnecessary.In some situations it is acceptable to use an apostrophe to clarify a plural for lower case letters only - again, the Oxford Dictionary states that it is incorrect to use it for capitals. ABCs is correct. ABC's is not.
