Q6) The random variables \( X \) and \( Y \) have the joint PMF \[ P_{x, y}(x, y)=\left\{\begin{array}{ll} \text { dir+y| } & x=-2,0,2 \\ 0 & y=-1,0,1 . \\ \text { ethervis. } \end{array}\right. \] The value of the constant \( c \) is A) \( 1 / 6 \) B) \( 1 / 16 \) D) \( 1 / 12 \)

Setting up the equation to find c : The joint PMF of the random varia
