Answer:
1000 possible combinations
Explanation:
For the padlock combination code, each number can be one of 10 (0-9).
This means there are 10 possibilities for the first digit, 10 for the 2nd, 10 for the 3rd, and 10 for the 4th.
If we combine all these possibilities between the different digits we get:
10 x 10 x 10 x 10 = 1000 different combinations.
Hope this helped!
