NO! The lesson has a theorem that says that X,Y are independent if and onlyif you can write f(x,y)=a(x)b(y) with no funny limits for somefunctions a(x) and b(y). Can't do such a factorization, so X and Y ain't indep.Quiz Score:10out of 11PreviousNextSubmission Details:Time:6,702 minutesCurrent Score:10 out of 11Kept Score:10 out of 11
