To find how many numbers between 1 and 885 have seven as one of their digits, we can analyze the numbers from 1 to 885. We can count the occurrences of the digit '7' in the units, tens, and hundreds places within this range. The total count reveals that there are 271 numbers between 1 and 885 that contain the digit '7'.
A binary number consists of two possible digits: 0 and 1. When using seven digits, each digit can independently be either 0 or 1. Therefore, the total number of binary numbers that can be formed with seven digits is (2^7), which equals 128. Thus, there are 128 different binary numbers that can be written using seven digits.
