Re: probability and statistics demo for kids

I'm a big fan of Galton Boards:

Python + Dice idea = Simple Code

http://www.pythonforbeginners.com/code-snippets-source-code/game-rolling-the-dice/

I'd introduce the idea that 1 die = Uniform Probability but 2+ dice =
Binomial distribution (because there are more ways to roll some numbers,
e.g. 7 than others, e.g. 12).

A Python generator for Pascal's Triangle (= Binomial Distribution):

def pascal():
    row = [1]
    while True:
        yield row
        row = [i+j for i,j in zip([0]+row, row+[0])]


gen = pascal()

for _ in range(10):
    print(next(gen))

[1]
[1, 1]
[1, 2, 1]
[1, 3, 3, 1]
[1, 4, 6, 4, 1]
[1, 5, 10, 10, 5, 1]
[1, 6, 15, 20, 15, 6, 1]
[1, 7, 21, 35, 35, 21, 7, 1]
[1, 8, 28, 56, 70, 56, 28, 8, 1]
[1, 9, 36, 84, 126, 126, 84, 36, 9, 1]
