Question: What is the half-life of radioactive dice?
No, really! It’s a serious question (well, half-serious, anyway!)
Definitions: By definition, a radioactive die is one that spontaneously disintegrates if it’s thrown six uppermost. And the half-life is the length of time you have to keep throwing lots of radioactive dice until you are left with exactly half the number you started with (ok, I know you don’t actually have any to start with – use your imagination!). “Time” here is measured in number of throws, of course.
