Nick_Tarleton comments on Drawing Two Aces

[Nick_Tarleton]

Throw darts at a unit square, take the fraction that hit a point (x < .7, y < .5) and multiply by 100. (Also works to calculate pi.)

[Zack_M_Davis]

I get 36.0.

#!/usr/bin/python
 from random import random
 trials=200
 hits=0
 for i in range(trials):
         x=random()
         y=random()
         if x<.7:
                 if y<.5:
                         hits+=1
 print 100*(float(hits)/float(trials))

It’s samping variation. Set trials = 1e9 and see what you get.

If I knew how to take fractions, I would have just done 7/​(1/​5).
