Mathematical expectation

I'm the one who wrote the "Mathematical expectation" section. I'm not really good at math so I want you to check the program I used to calculate the data. It's written in Python 2:

one=1
five=2
x5=3
bowser=4

import itertools

l=[one,one,one,one,five,five,five,x5,x5,bowser,bowser]
p=itertools.permutations(l,5)                              # change to 7, 9

def coins(l):
    l=list(l)
    s=0
    while len(l):
        a=l[0]
        del l[0]
        if a==one:
            s+=1
        elif a==five:
            s+=5
        elif a==x5:
            s*=5
        elif a==bowser:
            s=0
            break
        else:
            raise NameError('wtf?')
    return s

ans=[coins(l) for l in p]
s=sum(ans)

print s/len(ans)
print s
print len(ans)

The result is:

11
661200
55440

11
18385920
1663200

3
71245440
19958400

Since the 9-Block Option has a bonus, the real number of coins earned is 6.

I daren't calculate the variance because my machine is slow. Another gossip-loving Toad (talk) 22:32, 20 October 2014 (EDT)
