My solution for The Random Challenge is different but seems to work.

Will the following:

Math.floor(Math.random() * secondNumber) + firstNumber

produce the same result as:

Math.floor(Math.random()*(secondNumber - firstNumber + 1)) + firstNumber

if used as part of The Random Challenge?

My code is as follows and seems to work:

var firstNumber = parseInt(prompt("Please enter your first number"));
var secondNumber = parseInt(prompt("Please enter your second number"));
var randomNumber = Math.floor(Math.random()*secondNumber)+firstNumber;

document.write("<p>A random number between " + firstNumber +  " and " + secondNumber +  " is " + randomNumber +  "</p>");

If it works, that's great! It doesn't have to be the same code, it just gotta' work. Although the Mr McFarland uses might be more efficient.
