Let \(X\) and \(Y\) have a uniform distribution on the set of points with integer coordinates in \(S=\{(x, y): 0 \leq x \leq\) \(7, x \leq y \leq x+2\}\). That is, \(f(x, y)=1 / 24,(x, y) \in S\), and both \(x\) and \(y\) are integers. Find

(a) \(f_{X}(x)\).

(b) \(h(y \mid x)\).

(c) \(E(Y \mid x)\).

(d) \(\sigma_{Y \mid x}^{2}\).

(e) \(f_{Y}(y)\).
