Imperfect Information notes
The Economics of Imperfect Information, I: Probability
Everyone is familiar with probability to some degree, from
rolling dice, playing cards, and so on.
Basic postulate of probability theory:
events range from impossible
The Principle of Aggregation
When you roll a single die, you are highly uncertain about
how the roll will turn out. It is equally likely to be anything
between 1 and 6.
But when you roll ten dice and add the sum, your level of
