Question
Assume thatY1,Y2, andY3are random variables, with: E(Y1) = 2, E(Y2) =1, E(Y3) = 4, V(Y1) = 4, V(Y2) = 6, V(Y3) = 8, Cov(Y1, Y2)
Assume thatY1,Y2, andY3are random variables, with:
E(Y1) = 2, E(Y2) =1, E(Y3) = 4,
V(Y1) = 4, V(Y2) = 6, V(Y3) = 8,
Cov(Y1, Y2) = 1, Cov(Y1, Y3) =1, Cov(Y2, Y3) = 0.
(a) FindE(3Y1+ 4Y26Y3).
(b) What isV(3Y1+ 4Y26Y3)?
