## 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 surprising result. 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,...

## What’s the probability you live in an odd-numbered house?

James Grime makes some fantastic videos. Here’s an excellent investigation into whether more people live in even or odd numbered houses with an interesting result! This would make for a great lesson on relative frequency!
