  2. Why can/can't I find my number in Pi?

    If we view Pi as a big, random string of numbers (which is close enough for our purposes), then we can figure out the odds of finding any string in the first 100 million digits of Pi:

    Number Length Chance of Finding

    1-5 100%

    6 Nearly 100%

    7 99.995%

    8 63%

    9 9.5%

    10 0.995%%

    11 0.09995%

    Happily, if you include the zeros, birthdays are 8 digits long -- so you have a 63% chance of finding your birthday in the first 100 million digits of pi. Note that if I added another 100 million digits, these odds would only go up to 86%, so it'll be a while before everyone can find their birthday in Pi.

     

    I've also posted a more in-depth explanation of the probability of finding strings in Pi for people who are curious.
