Advanced Math:Toothpick drop activity

In 1777, Count Buffon proposed dropping a needle on lined paper and asking for the probability of the needle crossing a line. The answer surprisingly is related to pi. The students make 100 drops of a toothpick (one unit length) onto paper with lines one unit apart. The students count the number of times that the toothpick crosses the lines Ð this is a hit. The ratio of hits to 100 approaches 2 / Œ. Pi can be approximated by two times the number of drops divided by the number of hits.
