Execute function based on percentage given

So I have two functions

   function toWin(){
      console.log('win')
   }

   function toLose(){
      console.log('lose')
   }

how do I get each functions to be executed based on the percentage given? Say in 100 tries, toWin() should be executed 90 times, and randomly.

I'd like to change the win_percentage to any number any time.

   var win_percentage = 90; // 90 percent

   function generateResultRandomly(){
      //code to execute either function should be here.
   }

If there's any other way I can get this without my methods, it'll be appreciated, or you could help in writing the algorithm and I code it out.

Try this

var win_percentage = 90; // 90 percent

function generateResultRandomly(){
  var random = Math.floor(Math.random() * 101); // returns a random integer from 0 to 100
  if (random <= win_percentage) {
      toWin();
  } else {
      toLose();
  }
}
