// Between any two numbers
Math.floor(Math.random() * (max - min + 1)) + min;

// Between 0 and max
Math.floor(Math.random() * (max + 1));

// Between 1 and max
Math.floor(Math.random() * max) + 1;

console.log(Math.round(Math.random() * 10))

function getTotal(){
    var total=0;
    for(let t=0; t<array.length; t++){
        total+= array[t].randomNum;
