For
this question, I really confused about why a=this thing. Also,
could you please tell me the specific steps of the thing that I
highlighted in a red pen? I really don’t know how to use math to
deal with it. Finally could you tell me how to calculate
Var(3X1),VarX2 and Cov(3X1-X2)? Thanks! Will rate:)
