基于总比赛损失和总投注的输赢率

Question

我试图根据他们输掉的球员总比赛和投注总投注，以数学方式计算出球员赢球损失率？

例如：

Wins = 1
Loses = 111
Played = 112 
Total = 500
Won = 100 
Lost = 400
Percent = 0.8928571428571428  

赢/输比率：

var wins = 1;
var loses = 111;
var percent = wins / (wins + loses) *100; //(1 / (1 + 111)*100)
//percent = 0.8928571428571428

将花费的“总”金额和“游戏总数”用于获得最佳比率的最佳方式是什么？

基于总花费和损失的比率：

var total = 500;
var lost = 400;
var loses = 111;
var ratio = lost / loses;
    ratio = ratio / total;
    //ratio = 0.032175032175032175;

任何帮助将不胜感激！
