Recently I had occasion to pose a question "which is more likely, flipping 10 heads in a row with a normal coin or getting four sixes in a row with a normal six sided die/dice". I asked a couple of people to work it out in their heads and was interested that there are a few different approaches. How would you decide which is more likely? What calculations would you do? What do you already know without needing to calculate that you can use to help?
