Theory 1
Memorize this info!
Bernoulli:
- Indicates a win.
Binomial:
- Counts number of wins.
- These are
times the Bernoulli numbers.
Geometric:
- Counts discrete wait time until first win.
Pascal:
- Counts discrete wait time until
win. - These are
times the Geometric numbers.
Poisson:
- Counts “arrivals” during time interval.
Theory 2
Uniform:
- All times
equally likely.
Exponential:
- Measures wait time until first arrival.
Erlang:
- Measures wait time until
arrival.
Normal:
- Limiting distribution of large sums.
