a) If X~Bin(45,0.6), what is E[X]?
b) If X~Bin(45,0.4), what is Var[X]?
a)
E(X) = np = 45 * 0.6 = 27
b)
Var(X) = npq
= 45*0.4*0.6
= 10.8

(e) Suppose that 4 balls are placed sequentially into one of 5 bins, where the bin for each ball is selected at random. For i = 1, 2,3,4,5, define the indicator variables 1, if the ith bin is empty; 0, otherwise Xi _ Then the number of empty boxes is given by X = X\+X2+ X3 + X4+X5, and we learned from week #7 lecture notes and midterm II that Xi ~ Bernoulli(p) with p = (1 - 2)4 =...
