Explanation:

Step1: Identify the shortest bar

By observing the bar - graph, the bar for white color is the shortest.

Step2: Determine the number of white T - shirts

The height of the white - color bar corresponds to 4 on the vertical axis, so 4 white T - shirts were sold.

Step3: Find the number of black and white T - shirts

The number of black T - shirts sold is 6 and the number of white T - shirts sold is 4.

Step4: Calculate the difference

The difference is \(6 - 4=2\).

Step5: Count the colors with at least 10 T - shirts

The red color has 10 T - shirts sold and the blue color has 12 T - shirts sold. So there are 2 colors with at least 10 T - shirts sold.
