Combination followed by permutation: 6 C 3 X 3 P 3 = 120
Explanation:
Selection of 3 from 6 can be done in 6 C 3 = 6 X 5 X 4 1 X 2 X 3 = 20 ways.
From each selection of 3 distinct digits, the digits can be arranged, differently, in 3 P 3 = 3 X 2 X 1 = 6 ways.
So, the number of 3-git numbers formed = the product
20 X 6 = 120.
