Demo Code

using System;/*w  w  w. j a v a2  s  . c  om*/
class RollDie

   static void Main()

      int frequency4 = 0; // count of 4s rolled
      int frequency5 = 0; // count of 5s rolled
      int frequency6 = 0; // count of 6s rolled
      for (int roll = 1; roll <= 60000000; ++roll)

         int face = randomNumbers.Next(1, 7); // number from 1 to 6
         switch (face)
         {
            case 1:
            ++frequency1; // increment the 1s counter
            break;
