Distributions

A list of shares that add up to one, what that one constraint buys you, and what a share does not tell you about what is going to happen.

Read in order

  1. A distribution fixes the totalWhen several outcomes share one fixed whole, what does a distribution commit you to, what does that fixed total let you calculate, and what can no single share say?
  2. Drawing at randomA list of shares says what could happen and how much of the total each outcome holds. How do you get one actual outcome out of it, and when does the chance of several outcomes together become a multiplication?
  3. Average and spreadOne number can stand in for a whole list, and a second number can say how badly it stands in. What are those two numbers, and what does each one hide?
  4. Telling a real difference from noiseTwo options are tried the same number of times and one records more successes. When does that mean it is better, and how many tries does it take before the answer is worth anything?
