The first letter can be any one of 22. For each of these ...The second letter can be any one of the remaining 21. For each of these ...The third letter can be any one of the remaining 20.So the number of different 3-letter line-ups is (22 x 21 x 20) = 9,240.That's the answer if you care about the sequence of the letters, i.e. if you call ABC and ACB different.If you don't care about the order of the 3 letters ... if ABC, ACB, BAC, BCA, CAB, and CBA are allthe same to you, then there are six ways to arrange each group of 3 different letters.Then the total number of different picks is (9,240/6) = 1,540.

The number of 3 letter different combinations that can be made from 10 differentletters is given by: 10C3 = 10!/[3!(10-3)!] = 120different 3 letter combinations.The number of three letter different permutations (one given 3 letter combinationgives 3! = 6 different permutations, e.g., the combination abc gives the 9permutations, abc, acb, bac, cab, bca, cba) is given by 10P3 = 10!/(10-3)! = 720different 3 letter permutations.The symbol (!) is the operator called "factorial" and it implies the multiplication:n! = n∙(n-1)! = n∙(n-1)∙(n-2)! = n(n-1)(n-2)(n-3)...(4)(3)(2)(1)(0!)where 0! = 1.i.g., 6! = 6∙5∙4∙3∙2∙1 = 720
There are 26 letters in the song ABC or in the alphabet
you use nPr, when you want to take note of the order. Example, in choosing between A,B,C,D & E , how many ways can you choose any 3 arranged letters. (This means ABC is different from ACB or BCA or...) Then 5P3. you use nCr , when the order is not important. Example , how many ways can you get three letters from A,B,C,D & E. (here ABC is no different from BAC since you just got A&B&C.) Then 5C3. I got this from yahoo answers :P
In the English language, the alphabet has 26 letters.
Six ways.
The alphabet we use in the United States, has a total of 26 letters.
it is the letters
well qwerty keyboards are different form abc keyboards to tell if the keyboard is qwerty or not look along the top row of letters abc keyboards will say abc at the top qwerty keyboards will say qwerty at the top sorry if this is not the answer you want wrong! The answer is, that QWERTY is the first Six letters of the keyboard on the top left side.
It depends on whether they are being arranged in a line or a circular pattern. In a line: 15*14*13 = 2730 ways. In a circular pattern : ABC, BCA and CAB will be the same pattern, only rotated. So the answer is 15*14*13/3 = 910 ways.
There are many different ways to print out a random sequence of letters on the screen. I believe that the shortest possible line of code that does this is: System.out.println("abcdcba abc cba"); For a program, here is the shortest program that runs on a Java 1.6 compiler: public class A{public static void main(String... a){System.out.println("abcdcba abc cba"
White lower case letters "abc" inside a black circle.
letters later numbers
Because a,b, and c are the first three letters of the alphabet
