Let $S_{0},S_{1},S_{2},\dots$ be an infinite sequence produced by a source $\mathcal{S}$. All $S_{n}$ take values in $\{0,1\}$, and $S_{n+1}$ depends only on $S_n$, that is, $p_{S_{n+1} | S_0, \dots, S_n}(s_{n+1} | s_0, \dots, s_n) = p_{S_{n+1} | S_n}(s_{n+1} | s_n)$. The probability $p_{S_{n+1}|S_{n}}$ is schematically represented in the graph below: egin{center} ikzset{ state/.style = { draw, circle, minimum size = 20pt, font = ontsize{12}{12}\selectfont, } } egin{tikzpicture}[> = latex]
ode[state] (a) {$0$};
ode[state, right of = a] (b) {$1$}; \path[->] (a) edge[bend left, above] node {$1/2$} (b); \path[->] (a) edge[loop left] node {$ rac{1}{2}$} (); \path[->] (b) edge[bend left, below] node {$1/4$} (a); \path[->] (b) edge[loop right] node {$ rac{3}{4}$} (); \end{tikzpicture} \end{center} For instance, the edge from $0$ to $1$ means that $p_{S_{n+1}|S_{n}}(1|0) = rac{1}{2}$. We also have that $p_{S_0}(0)=1$. True or false: For every $n\geq 0$, $H(S_n|S_0,\ldots,S_{n-1})
