Waiting time for a person row of a bank is defined by a VA X The distribution function that defines the probability that the person waits between 0 and 2 minutes is F(x) = (×^2)/6 and that of which w
\[ F(x)=\frac{x^{2}}{6} ; \quad F(x)=2 x-\frac{x^{2}}{3} \] El tiempo de espera de una persona en la fila de un banco está definido por una VA X. La función de distribución que define la probabilid1 answer -
a) Check f(x, y) that 4xy if 0≤x≤ 1, 0≤ y ≤ 1 to 0 otherwise it is a joint density function. b) If X and Y are random variables whose joint density function is the function of part a), find
a) Compruebe que \[ f(x, y)=\left\{\begin{array}{ll} 4 x y & \text { si } 0 \leqslant x \leqslant 1,0 \leqslant y \leqslant 1 \\ 0 & \text { de lo contrario } \end{array}\right. \] es una función de1 answer
