My first thought was that maybe some M&M colors are just more common than others. Like, perhaps there is some technical reason why the yellow M&M machine suffers more downtime than the blue M&M machine.
Then I figured that was nonsense, and that the color breakdown in my bag was a strange, but not unexpected, deviation. What I should do is get a bag every night for a month and keep track of the color distribution, expecting the count to break about even after a while.
But then I thought, wait, maybe color distribution will be similar through bags packaged at around the same time? What if every bag in the office vending machine has four times as many blues as yellows? In order to get a truly random sample, I should buy a bag of M&Ms at a different location every night for a month, just to make sure the spread is as even as possible.
While I was at it, I might as well keep track of partial or missing Ms. You know, for science.
Then I came to my senses and just ate my frickin’ candy. I bet we’ve all had days like this.
