• A) \(\left[ \begin{array} { c c } \frac { 16 } { 33 } & - \frac { 1 } { 33 } \\ - \frac { 1 } { 33 } & \frac { 2 } { 33 } \end{array} \right]\)
• B) \(\left[ \begin{array} { c c } \frac { 16 } { 33 } & \frac { 1 } { 33 } \\ \frac { 1 } { 33 } & \frac { 2 } { 33 } \end{array} \right]\)
• C)
• \[\left[ \begin{array} { c c }
• \frac { 16 } { 33 } & - \frac { 1 } { 33 } \\
• \frac { 1 } { 33 } & - \frac { 2 } { 33 }
• \end{array} \right]\]
• D) \(\left[ \begin{array} { c c } - \frac { 16 } { 33 } & - \frac { 1 } { 33 } \\ \frac { 1 } { 33 } & \frac { 2 } { 33 } \end{array} \right]\)
• E) \(\left[ \begin{array} { c c } \frac { 16 } { 33 } & - \frac { 1 } { 33 } \\ \frac { 1 } { 33 } & \frac { 2 } { 33 } \end{array} \right]\)
