The triple integral of a function f(x, y, z) over a rectangular box B is defined as. Show that X X, Y Y, and Z Z are pairwise independent. FZ(z) =∫∞ −∞∫z−x −∞ fX,Y(x, y)dydx F Z ( z) = ∫ − ∞ ∞ ∫ − ∞ z − x f X, Y ( x, y) dydx. I know Fz(z) = ∬ f(x, y)dxdy F z ( z) = ∬ f ( x, y) d x d y . Answer link. This divides into two parts. Advantages of Canonical Form: Uniqueness: The canonical form of a boolean function is unique, which means that there is only one possible canonical form for a given function. How is the transformation of f(x,y) = 1 to f(z) where Z=XY carried out? P(X ≤ t) = Z fX(x) dx. The function g(x,y,z,w)=(x+y+z')(x'+y'+w)+xyw' is also a Boolean function.
