The mean of the distribution represented by the histogram is 3.25
The mean is the product of the value of X and its corresponding probability (P(x)).
The mean can be expressed thus :
From the histogram :
Mean = (1 × 0.05) + (2 × 0.2) + (3 × 0.35) + (4 × 0.25) + (5 × 0.15)
Mean = 0.05 + 0.40 + 1.05 + 1.00 + 0.75 = 3.25
Therefore, the mean value of the distribution depicted by the histogram ls 3.25
