Probability help .

    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.


    I am trying to figure out the maximum number of divination in the losing direction
    so occurrences 500.

    Since your chance of losing is .2, the chances of losing k times in a row (assuming independence of the trials) is .2k.

    Your last sentence has typos - I can't understand it.
