How many binary numbers can be written using seven digits?

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.


A whole numbers consists of the digits 2468 and 0 if each digit is used only once how many whole number are possible?

To form whole numbers using the digits 2, 4, 6, 8, and 0, we must ensure that the number does not start with 0. The valid digits for the first position are 2, 4, 6, or 8, giving us 4 choices. After selecting the first digit, we have 4 remaining digits (including 0) to arrange in the other positions. Therefore, the total number of whole numbers is calculated as (4 \times 4!), resulting in 96 possible whole numbers.
