Calculating the frequency of the sum of the rolling of a pair of dice.

Question:

Java program to calculate the frequency of the sum of the rolling of a pair of dice.

Code:

public class RollDice {
 
   public static void main(String[] args) {
 
      int frequency[] = new int[13];
 
      int total=0;
      for (int roll = 1; roll <= 5000; roll++) {
         total = 1 + (int) (Math.random() * 6);
         total = total + 1 + (int) (Math.random() * 6);
         frequency[total] = frequency[total] + 1;
      }
 
 
      System.out.println("Total\tFrequency");
      for(int n=2;n<frequency.length;n++){
         System.out.println(n + "\t" + frequency[n]);
      }
 
   } 
}

Output:

$ java RollDice
Total Frequency
2 141
3 275
4 424
5 579
6 674
7 821
8 705
9 560
