/*
* Dice Game
*
* Problem 205
* Peter has nine four-sided (pyramidal) dice, each with faces numbered 1, 2, 3, 4.
* Colin has six six-sided (cubic) dice, each with faces numbered 1, 2, 3, 4, 5, 6.
*
* Peter and Colin roll their dice and compare totals: the highest total wins. The
* result is a draw if the totals are equal.
*
* What is the probability that Pyramidal Pete beats Cubic Colin? Give your answer
* rounded to seven decimal places in the form 0.abcdefg
