Dice probabilities

[dm319]

Oh that is fascinating.

So you are using the powers of x and the distributive law to 'add up' the powers of x and therefore essentially generate the crossing of 0, 1, 2.

Are you just using the convenience of this in order to calculate that - because I don't think there is anything inherently 'squared' about a die with two dots, or I may be missing something.

Also I imagine it took a while to expand out?
