theoretical outcomes nrich simulations

NRich have developed simulations
cosy corner
twos company

these are for two of Geoff Giles' DIME material probability experiments (no longer available unfortunately)

trials can be simulated and then compared with a theoretical analysis

I think a theoretical consideration is difficult
a teacher could present an argument
and then see if students can recreate it

these are diagrams from Geoff Giles' materials
