Question part ii. CS1:05 Page 7 Is there a way of working out to obtain f(x) = 6/5*x(x+1) Starting from E[Y|X=x] The solution to the part ii of the question refers to the f(x) given in an earlier solution but that solution started from f(x,y) to derive f(x)
you can work f(x) simply from f(x,y) by doing this: integrate from 0 to 2 f(x,y) wrt y 0->2 : 3/5*x(x+y) dy
