THE M-AND-MS INVESTIGATION PAGE

Purpose:
An ongoing investigation into the proportions of colours in the
55g M-and-Ms packet. There are six colours: brown, red, green,
yellow, orange and blue. My aim is to uncover any instances of
bias or favour in the proportions of colours in each packet,
and overall. 
Materials:
A number of 55g M-and-Ms packet, and a calculator.
Method:
1. Buy packet of M-and-Ms.
2. Open packet. Count and record the number of each colour.
3. Eat M-and-Ms.

Preliminary results:
So far brown is by far the favoured colour in the 55g M-and-Ms 
packet, with almost 30%. An even distribution would be 16.6%. The 
other colours are fairly even, with the exception of orange
and yellow, with just under 12% each. 

Note: An asterisk (*) next to the number of colours in a
packet indicates that the contents were crushed, therefore the
results may not be entirely accurate.
