Expert Solution
Step 1

We want to find expected balue of each distribution and also standard deviation. 

E(x)= xi×P(X=xi)

Var(x)= E(x2) - (E(x))2

Standard deviation=sqrt(variance)

 

Note:-According to Bartleby Expert guideline, we can answer only first three subparts of a question and rest can be reposted
