How many four-digit numbers are there between 7500 and 9600 that can be formed using only the digits 3, 7, 5, 6, 8, 9 without repetition of any digits?
Question
Solution 1
Sure, let's break this down:
The first digit can only be 7, 8, or 9 because the number must be between 7500 and 9600. So, there are 3 options for the first digit.
The second digit can be any of the remaining 5 digits (since we've used one for the first digit and we can't repeat digits). So, Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
