Using that formula, indices 0 and 5 have only half the chance of being
returned as indices 1 to 4, so not a very random selection. Use floor
or ceil for an even distribution, for speed use:
var bioIndex = (Math.random()*6) | 0;
which is the same as using Math.floor. To return a random integer
between 0 and n, use:
function getRandomInt(n) {
return Math.random()*n | 0;
}
