编写一个脚本来模拟掷两个骰子。脚本应该使用Math。随机掷出第一个骰子，再掷出第二个骰子。然后计算这两个值的和。[注:由于每个骰子都可以显示1到6的整数，所以数值的总和从2到12不等，其中7是最常见的和，2和12是最不常见的和]。您的程序应该掷骰子5000次。使用一个一维数组来计算每个可能的和出现的次数。在HTML5表格中显示结果。

我只有和谁能告诉我如何在一个表格中得到从2到12的掷骰子的和

    var total = [ , , 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0];
    var dice1;
    var dice2;
    for (var x = 1; x <= 5000; x++)
    {
    dice1 = rollDie();
    dice2 = rollDie();
    ++total[dice1+ dice2];
    }
    outputResults();
    function rollDie()
    {
    return Math.floor(1 + Math.random() * 6);
    }
    function outputResults()
    {
    document.write( "<table border = '"1'">" );
    document.write("<tr><th width = '100'>Sum of Dice" +"<th width = '"200'">Total Times Rolled</tr>" );
    for ( var i = 2; i < total.length; i++ )
    document.write( "<tr><td>" + i + "<td>" +total[ i ] + "</tr>" );
    document.write( "</table>" )
    document.write( "<br>" );
    document.write( "<br>" );
    document.write( "<table border = '"1'">" );
    document.write("<tr><th width = '100'>Sum of Dice" +"<th width = '"200'">Total Times Rolled</tr>" );
    for ( var i = 2; i < total.length; i++ )
    document.write( "<tr><td>" + i + "<td>" +total[ i ] + "</tr>" );
    document.write( "</table>" );
    }
    <p id="jareb"></p>

遍历total中的所有sum并将它们相加:

var sumOfAllDice = 0;
for(int i=2; i<=12; i++) {
   sumOfAllDice += total[i];
}
document.write('<p>'+sumOfAllDice+'</p>');


var total = [,,0,0,0,0,0,0,0,0,0,0,0,0]
var count = [,,0,0,0,0,0,0,0,0,0,0,0,0]
function write(){
  var html="";
  for(var i=2; i<=12; i++){
    html += ("The Sum of "+i+" occurred :"+count[i]+" Times and Total : " + total[i] + "<br/>");
  }
  
  document.write(html);
}
function roll(){
  var d1 = Math.floor(1 + Math.random() * 6);
  var d2 = Math.floor(1 + Math.random() * 6);
  count[d1+d2]++;
  total[d1+d2] += d1+d2;
}

for(i=1;i<=5000;i++)
  roll();
write();
This is the result!
