\[\boxed{\mathbf{288.}}\]

\[Всего\ событий:N = 36.\]

\[\textbf{а)}\ N(A) = 6:\]

\[P = \frac{6}{36} = \frac{1}{6}.\]

\[\textbf{б)}\ N(A) = 2:\]

\[\left\{ (5;6);(6;5) \right\}.\]

\[P = \frac{2}{36} = \frac{1}{18}.\]

\[\textbf{в)}\ N(A) = 15;\]

\[P = \frac{15}{36} = \frac{5}{12}.\]

\[\textbf{г)}\ N(A) = 24;\]

\[P = \frac{24}{36} = \frac{2}{3}.\]
