The Poisson distribution — practice question

Every week, the Redbury United soccer team takes part in one match. Each match results in a win, a draw or a loss. At the beginning of the soccer season, the probability that Redbury United win their first match is $\frac{3}{5}$, and the probabilities of losing or drawing are equal. If they win the first match, the probability that they win the second match is $\frac{7}{10}$ and the probability that they lose the second match is $\frac{1}{10}$. If they draw the first match they are equally likely to win, draw or lose the second match. If they lose the first match, the probability that they win the second match is $\frac{3}{10}$ and the probability that they draw the second match is $\frac{1}{20}$.
