To determine the number of 4-digit numbers that can be formed using the digits 5, 6, 7, and 8 without repetition, we use the concept of permutations. Since there are 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the fourth digit, the total number of 4-digit numbers is calculated as 4 x 3 x 2 x 1 = 24. Therefore, there are 24 different 4-digit numbers that can be formed using the digits 5, 6, 7, and 8.
5678 is only one 4-digit number. If you're willing to move the digits around to different positions, you can make 23 more.
add them all together and then divide the answer by the number of numbers.
