Explanation / Answer

we see that the sum of the probabilities 0.03+0.13+0.26+0.24+0.19+0.15 = 1. Hence this is a probability distribution table. Multiplying each quantity with its probability and adding we get

0 * 0.03 + 1 * 0.13 + 2 * 0.26 + 3 * 0.24 + 4*0.19 + 5*0.15 = 0 + 0.13 + 0.52 + 0.72 + 0.76 + 0.75 = 2.88

The mean is 2.88
