Question no 1 is difficult .
brother is it complete answer Q1 ? or calculated E(X) or E(Y) and E(XY)? If these calculated plz in detail solved how these E(X) or E(Y) and E(XY) calculated?
Q2 i 've solved it was easy.

who said to calculate E(X)&E(Y) E(XY) in q 1? i dont think they are needed to calculate bcz they dont tell about independence of X & Y

Part c of Question-1 is easy you can calculate by taking product of g(x) and h(y) and comparing it with the joint distribution function.

Zain bhai samajh ni ai ap ki bat ki kis trh product le kr compare karen gy r kis k sath compare karen gy.......

zubair bro see this

E(XY)=E(X)*(Y)
=0.4*1.9
=0.76
right or wrong please tell me.
