What is the range?7     2     0     9     6     4     1

The range of a set of numbers is the difference between the highest and lowest values in the set.

Here are the steps to find the range:

1. Identify the highest number in the set. In this case, the highest number is 9.
2. Identify the lowest number in the set. In this case, the lowest number is 0.
3. Subtract the lowest number from the highest number.

So, the range is 9 - 0 = 9.
