+ * 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
