    A daily pick....if something has a 1 in 7 chance of hitting and it does hit 9 out of 10 days, what are those odds? Any help?

    How's this?
    (((((((.142 x .142) x .142) x .142) x .142) x .142) x .142) x .142)

    Each step of the way:
    0.142857
    0.002863
    0.000407
    0.000058
    0.000008
    0.000001
    0

    It's almost zero chance at 9 in a row.

    Thanks. This is a lottery issue, not roulette. I like the roulette section better (lol). A doubler (per day) might be drawn. There is a 1 in 7 chance it'll be drawn. This was back in Dec. Look at this shit. 9/10, its a doubler !?
