This dice has 3 1s and 3 0s on it. So if you need to decide between doing something and not doing something, this is the dice for you.
But couldn't you just toss a coin? No. Coins are for deciding between two similar things like sports teams as opposed to deciding between [thing] and [not thing].
But couldn't you just use a regular dice and map the numbers to 1 and 0? Look do you want the dice or not?
