Nebraska Lottery, odds of 1 in a million?

  1. Jan 28, 2009 #1

    Headline says: "Neb lottery draws same numbers twice in a row. The odds of such an occurance? One is a million.

    To begin with it was not the lottery, it was the pick 3, the number being 196. One in a million???

    If you have a 3-digit number to guess, you have one chance in a thousand of nailing it. What are the chances that you will be successful on a successive draw using ANY numbers (not just the same numbers)?

    Clearly they are using base 100.

    Heh. The three people who won that whopping $600 must be feeling a little short changed. After all, it was a one-in-a-million event, right? :smile: We live in a magical world.

    1 in a million if specified in advance of the two drawings; the usual 1 in 1000 after the first pick since they're independent

    There are six draws a week: Nebraska Pick 3, and thus 312 to 314 drawings per year (average 313.04..., call it 313). The expected number of times in a given year that a drawing repeats the previous one is 0.313. The chance that it happens in a given decade is 1 - .999^3130 = 95.6...%.
