This month's Challenge Question: Specs & Techs from GlobalSpec:
A gumball machine is half
filled with plain milk chocolate M&Ms and half filled with pretzel
M&Ms. The plain and pretzel M&Ms are perfectly mixed. After a
month the machine is almost empty and you put a coin in to get a handful of M&Ms. Are you more likely
to get more plain M&Ms or pretzel M&Ms?
And the answer is:
You
are more likely to get Pretzel M&Ms. Pretzel M&Ms are larger than plain
milk chocolate M&Ms. The smaller plain M&Ms pack more tightly which
force the Pretzel M&Ms towards the top over time. The extreme example of
this would be sand and marbles. Obviously a gumball machine filled with sand
and marbles would eventually have sand at the bottom and marbles at the top.
