Buffon’s Needle- a mysterious probability activity

Buffon’s Needle is a wonderful probability experiment you can do with a class that has a most┬ásurprising┬áresult. Out of a seemingly ordinary, unspectacular experiment involving dropping a pencil between a pair of parallel lines, the relative frequency is related to pi! Here is a superb website that explains the experiment and gives a derivation of why the results tend towards...


Experimental probability- bin it

If you’re looking for a nice task to introduce experimental probability, get pupils to throw scrunched up paper balls into the bin from a distance and recording their number of successes and misses. Pupils love this activity and you can get a lot of learning from it: demonstrating something that doesn’t have equally likely outcomes and so requires an experiment,...
