Geez, I haven't felt the urge to get this outright geeky in weeks, but I actually bothered to dust off the combinatorial probability to verifyJohn's numbers. It turns out that 100 trillion is a nifty approximation assuming the 1% figure (the actual number is closer to 1 in 121 trillion, but what's 21 trillion among fegs?).
Interestingly, the number of days Gary spent away from this sweet land o' liberty and the number of days he has been alive _do_ make a measurable difference to the numbers, even if their ratio (e.g., 1%) remains constant.
Gary, you didn't specify how many days you have spent outside this here country. If, in fact, the only days of your (temporary, and presumably voluntary) exile are the ones coinciding with those particular New Yorkshows, the odds of this freak occurrence drop to 1 in nearly 4,000,000,000,000,000,000,000,000, or 4 septillion (in the UK, I think the number's called something else). If, on the other hand, you've spent half of your 11,000 days in nations that don't rhyme with "esoterica," the likelihood jumps to a fathomable 1 in 128.24. Still, it's unlikely, to say the least.
Hey kids! Here's how you can play along at home! If d = the number of days you've been alive, and r = the number of dates Robyn is playing in your hometown this tour, and a = the total number of days you will have been (or were) in Europe/Mozambique/Upper Sandusky at the time of Robyn's gig in your neck of the woods, then the probability of your not being around for the show(s) is:
a!(d-r)!The ! signifies factorial, which is the number multiplied by all positive integers lower than it. For instance, 5! equals 5 x 4 x 3 x 2 x 1.
But then, if you're morally opposed to punctuation marks posing as mathematical operators, John's rule of thumb will give you a pretty bitchin' estimate.
