three probability experiments

looking initially at how many sixes you obtain when a dice is rolled 20 times

"how many sixes do you think we would normally get?"

class results can be amalgamated to compare a short run (one student, 20 throws) experiment with a larger experiment (whole class x 20)

exploring a simpler case, three rolls of a dice;
how many sixes do you get theoretically?
do the experiment a few times
does it seem to favour 'a' or 'b' or does it seem fair?
a theoretical analysis
can be analysed just using a sample space
