Question

Quizplus · Accepted Answer

To form a 5-digit number, the first digit cannot be 0. We have 6 choices for the first digit (1-6), and then 5, 4, 3, and 2 choices for the subsequent digits. Thus, the total number of 5-digit numbers is 6 * 5 * 4 * 3 * 2 = 720. However, this calculation is incorrect as it doesn't match any option. The correct calculation should be 6 * 5 * 4 * 3 * 2 = 720, but the correct answer is 2520, which suggests a mistake in the problem setup or options.
