For a description of this tutorial and the C# code please see the two coins tutorial.

IronPython script

# Infer.NET IronPython example: Two Coins  

import InferNetWrapper

 # The model  
 b = Microsoft.ML.Probabilistic.Distributions.Bernoulli(0.5)

 # The inference  
 engine = InferenceEngine()  
 print "Probability both coins are heads:", engine.Infer(bothHeads)
