One example I do is a simulation (actual will also do but will obviously take
more time) of throwing three coins and asking, "What is the proabibility of
getting two heads?" Students will initially say 2/3 etc. Do the simulation and
this should lead to an experimental probability of around 3/8. Then ask "What is
the theoretical reason for this?" It covers quite a lot of ground. TI84s are
great for this as they have an application builtin. They you can then weight
the coins etc. Plenty of scope for enrichment!
