What is the probability? Help

    What is the probability? Help....

    If i have a standard 80% chance of wining and 20% chance of losing
    than what is the chance of me losing 5 times in a row 10 times in a row
    and 20 times in a row.

    I would be very grateful if someone can show me how to calculate this on my own.

    In how many attempts? In 5 attempts, it's just p^5, where p is the chance of winning.

    Losing, you mean.
