Poisson distribution
Day 13 first.
Did a little Poisson; return to Day 13 work
next time.
X =Number of "hits" in a fixed interval of space
or time (interval can be area or volume)
Lambda = np = expected number of hits/successes in
the whole interval (whole n trials).
|___|_*_|___|___|__*|___|*__|___|
8 trials, 3 hits

Next: "Expectation" Ash Ch. 3: 3.1, 3.2 (& 3.4).
Expectation
of X = mean of X
M&M Means and Variances 4.4 pp317-330 (lightly over Laws
of Large Numbers). (Reading--zigzag between texts)
