title: evenly distributed random numbers
body: <p>Hey, is there way to choose evenly distributed random numbers? I used this function </p>
  
  <pre><code>Math.floor(Math.random()*2)
  </code></pre>
  
  <p>which returns either 1 or 0. However, I dont think it has exact 50% chance to produce either one. Better thoughts? Thank you </p>
