    You could think it through this way....

    If the team plays 100 games, 55 are at home and 45 are away.

    Number of home wins will be (0.8)55

    Number of away wins will be 0.65(45)

    As these are not whole numbers, we can increase the number of games to 10,000 if we like.

    However, if a game was won, the probability that it was a home game is

    \frac{number\ of\ home\ wins}{number\ of\ won\ games}

    .
    This is conditional probability. Use Bayes' Theorem (draw a tree diagram and use it to calculate the probabilities required in it). If yu need more help, please show what you've tried and say where you get stuck.

    (And in future, please type the question out.)
