four numbers

the powerpoint is here

thanks to Mike Askew for this question

it explores oddness and evenness
and divisibility by 4, including - possibly - a divisibility test for 4

and it can be set in the context of probability
finding all the outcomes, theoretically
maybe checking these by experiment
