Explanation

The first 10 whole numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Step 1: Arrange the numbers

The numbers are already in order.

Step 2: Find the median

Since there are 10 numbers (an even count), the median is the average of the 5th and 6th numbers.

5th number = 4

6th number = 5

Median = (4 + 5) / 2

= 9 / 2

= 4.5
