To find the mean of a distribution, we need to multiply each value by its corresponding frequency and then add up all of these products, and divide by the total number of values. Doing this for the values given in the histogram, we get:

(0.5 x 2) + (1.5 x 5) + (2.5 x 7) + (3.5 x 4) + (4.5 x 2) = 42

Dividing by the total number of values, which is 20, we get:

42/20 = 2.1

So the mean of the distribution is 2.1. The answer closest to this value is C: 2.32.
