• A) \[\begin{array} { l | l c r r }
• \mathrm { X } & 1 & 9 & 10 & 11 \\
• \hline \mathrm { P } ( \mathrm { X } = \mathrm { x } ) & 1 / 4 & 1 / 4 & 1 / 4 & 1 / 4
• \end{array}\]
• B) \[\begin{array} { l | l r r r }
• \mathrm { X } & 12 & 19 & 20 & 21 \\
• \hline \mathrm { P } ( \mathrm { X } = \mathrm { x } ) & 1 / 6 & 1 / 6 & 1 / 3 & 1 / 3
• \end{array}\]
• C) \[\begin{array} { l | l r r r r }
• \mathrm { X } & 12 & 19 & 20 & 21 & 22 \\

• \end{array}\]
• D) \[\begin{array} { l | l r r r r }
• \mathrm { X } & 2 & 12 & 19 & 20 & 21 \\
• \hline \mathrm { P } ( \mathrm { X } = \mathrm { x } ) & 1 / 12 & 1 / 12 & 1 / 6 & 1 / 3 & 1 / 3
• \end{array}\]
• E) \[\begin{array} { l | l r r r }
• \mathrm { X } & 12 & 19 & 20 & 21 \\
• \hline \mathrm { P } ( \mathrm { X } = \mathrm { x } ) & 1 / 4 & 1 / 4 & 1 / 4 & 1 / 4
