Probability [show on/over a graphic of one or two dice]


Probability is when you don’t know exactly what will happen, but you do have a range of options and you know how likely it is that each one will come up.

Imagine you’re rolling a dice. It has six sides, so there is one chance in six for any number on it. Of course if you actually roll a dice six times, you’re unlikely to get each number once – but if you keep rolling it, each number will come up one-sixth of the time. Though it might take hours of rolling dice for this to actually happen.

What would you bet on rolling a 1? A 2? How about an 8? Or a -1?

[It’s possible to get dice where one side comes up more often than others. They’re called loaded dice. But you can still describe the uncertainty with probabilities.]
