In how many ways can you arrange the numbers 2 4 6 and 8 to make a four-digit number?
24 (You said "arrange" rather than "use," so I assume you want to use each digit only once).There are 4 choices for the first digit. Once you choose it, you have 3 choices left for the second digit. Likewise, you have 2 choices for the third digit and only one choice for the 4th digit.Thus, you have 4 x 3 x 2 x 1 = 24 ways of making a 4 digit number with these digits.
