The luckiest gut in the world

I stopped in a 7-11 the other day for the first time in ages and noticed they’re doing the free iTunes pepsi contest with their slurpees. I always thought 7-11 did Coca Cola slurpees, but it’s all just sugary frozen brown stuff anyway so I decided to give it a chance.

Long story short: I’ve had three slurpees in the past week after not having one for almost a year — but I’ve won all three times. You gotta play to win, as they say.

Now, I could be extremely lucky (a 1 in 27 chance of winning three times in a row), or 7-11 could be making every slurpee a winner. I don’t know which hypothesis is correct, but I’m going to be collecting more data this week and I’ll be sure to let you know if I ever lose.
