A) Let F(a,b) be the joint distribution function of random variables X and Y. Then the marginal distribution function of X is given for each a by F,(a)=lim F(a,b) i) True ii) False B) The random variables X and Y, with joint distribution function F(a,b), are independent if: F(a,b)=Fx(a)Fy(b) ii) F(a,b)=Fx(a)+Fy(b) iii) F(a,b)=Fx(a)–Fy(b) i) iv) They are always independent
