<h3>What is permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Total unique numbers consists in a Sally locker = 3
From the digits 0 to 39
Total numbers = 40

= 9880
Thus, 9880 different possibilities are there in Sally's new combination option second 9880 is correct.
