What is the mean distribution
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Mean = Sum of products between corresponding x and P(x) values
Mean = 0*0.15 + 1*0.20 + 3*0.10 + 4*0.20 + 5*0.05
Mean = 0 + 0.20 + 0.30 + 0.80 + 0.25
Mean = 1.55
So the mean is 1.55
Remember that the mean is NOT a probability since it corresponds to the average x value.
