Explanation

To find the mean of a distribution, we multiply each value by its corresponding frequency, sum up the products, and divide by the total frequency.Value Frequency Product (Value * Frequency)0     1         0 * 1 = 01     2         1 * 2 = 22     2         2 * 2 = 43     1         3 * 1 = 34     9         4 * 9 = 36Total Frequency: 1 + 2 + 2 + 1 + 9 = 15Sum of Products: 0 + 2 + 4 + 3 + 36 = 45Mean = Sum of Products / Total Frequency = 45 / 15 = 3Therefore, the mean of the given distribution is 3.
