How many 3-digit numbers can be formed from the digits 0, 1, 2, 3, and 4 without repetition? The first digit cannot be 0.

Answer and explanation

Correct answer: 48 numbers

The first digit has 4 choices (1, 2, 3, or 4). After that, 4 digits remain for the second place and 3 for the third. Thus, the total is 4 × 4 × 3 = 48.
