Using the graph below, you have a samples space where each element is a valid path on the graph that does not include any vertex twice and must includes at least two vertices. For example, ACD and CB are valid paths but D and DCD are not.Define the random variable $X$ to be 1 when a path contains a $B$ and random variable $Y$ to be the length of the path.

We can reduce the sample space to paths which do not contain $B$ and then count those which have length $3$:
$$ \frac{3}{7} $$We can just count the number of length 3 paths that do not include $B$
$$ \frac{3}{18} $$No, because $P(Y=3) \neq P(Y = 3 | X = 0)$
We are being asked if $P(X, Z | Y) = P(X | Y) P(Z | Y)$ for all possible values of the rvs.
We can make a table for this expression. It will be convenient to know that $P(Y = 2) = 6 / 18$, $P(Y = 3) = 7 / 18$, $P(Y = 4) = 5 / 18$
$$ \begin{array}{lcc|cr} X & Z & Y & P(X, Z | Y) & P(X | Y) P(Z | Y)\\ \hline 0 & 0 & 2 & 2 / 6 & 2 / 6 \times 1\\ 1 & 0 & 2 & 4 / 6 & 4 / 6 \times 1\\ 0 & 1 & 3 & 5 / 7 & 5 / 7 \times 1\\ 1 & 1 & 3 & 2 / 7 & 2 / 7 \times 1\\ 0 & 1 & 4 & 0 / 5 & 0 / 5 \times 1\\ 1 & 1 & 4 & 5 / 5 & 5 / 5 \times 1\\ \end{array} $$So yes
No, for example
$$ P(X=1, Y=3 | Z=1) = \frac{2}{7} $$$$ P(X = 1 | Z = 1) P(Y = 3 | Z = 1) = \frac{7}{12} \frac{7}{12} \neq \frac{2}{7} $$
