1. Problem Description

The problem asks us to create a frequency table based on the given data. The data is a 3x3 grid of numbers, representing the number of windows in different rooms. We need to count the number of rooms with 0, 1, 2, and 3 windows.

2. Solution Steps

We need to examine the 3x3 grid:

```

2 2 2

2 0 2

2 3 2

```

and count how many times each number (0, 1, 2, 3) appears.

* Rooms with 0 windows: There is one '0' in the grid. So the frequency is

1. * Rooms with 1 window: There are no '1's in the grid. So the frequency is

0. * Rooms with 2 windows: There are seven '2's in the grid. So the frequency is

7. * Rooms with 3 windows: There is one '3' in the grid. So the frequency is

1.

3. Final Answer

0: 1

1: 0

2: 7

3: 1
