Question
Help me understanding this problem solution better where did the 6 come from is is it suppose to be standard deviation sign
![Elxy) = 6x +EWE)
вху
F(R1
E (XY)
= E(X - E (X) + EM) | (Y - E (1) +EG₂ |
E[(X-EIA) +E(X) ] [ (X- EIGA) + E(X)]
= E
= E (X-EM) (Y-E(Y) + E(Y) E(X-EC) + E(x) (Y-EG)) + E(X) E(y)]
