Calculating the Number of Different Even Two-Digit Numbers

To calculate the number of different even two-digit numbers that can be formed using the digits 1, 3, 2, and 0 without repetition, we can follow these steps:

1. Identify the Even Numbers: First, we need to identify the even numbers that can be formed using the given digits without repetition. 2. Count the Possibilities: Then, we count the number of different even two-digit numbers that can be formed.

Let's proceed with these steps.

Identifying the Even Numbers

The even numbers are those that end in 0, 2, 4, 6, or 8.

From the given digits 1, 3, 2, and 0, the possible options for the units place to form an even number are 0 and 2.

Counting the Possibilities

Using the given digits without repetition, we can form the following even two-digit numbers:

1. 10 2. 12 3. 30 4. 32

So, there are 4 different even two-digit numbers that can be formed using the digits 1, 3, 2, and 0 without repetition.
