Let \(Y\) be \(\operatorname{binomial}(n=5=6)\).
(a) Calculate the mean and variance by lling in the following table:

i. \(\mathrm{E}[Y]=\)
ii. \(\operatorname{Var}[Y]=\)
(b) Calculate the mean and variance of \(Y\) using Equations 5.7 and 5.8, respectively. Do you get the same results as in part (a)?

Equation 5.7 and 5.8
