Daniel: I suppose you could use Mathematica conditionals and loop
structures to perform your experiment, but, as you suggest, that would
not be the best way to go. Better to use functional constructs such as
Partition and Apply.Here is an example that takes only a second or two
to run ten thousand simulated dice rolls.
