Answer:

24 three-digit numbers

Step-by-step explanation:

  1. The first digit of the arrangement can be any 1 of 4 integers.
  2. The second digit can now be any 1 of 3 integers. So the first two numbers can be a combination of 4  ×  3  numbers or  12  arrangements.
  3. The third digit can be any 1 of the 2 remaining integers. So the first three numbers can be a combination of 4  ×  3  ×  2  numbers or  24  arrangements.

Therefore, we can form 24 three-digit numbers using integers 2, 3, 4, and 7.

I hope it helps! Thank you! ❤️
