The arr variable is [head,tail]

function randomChoice(arr) {
    return arr[Math.floor(arr.length * Math.random())];
    //returns the value of head or tails
}

The Math.random() function returns a floating-point, pseudo-random number in the range 0–1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range. The implementation selects the initial seed to the random number generation algorithm; it cannot be chosen or reset by the user.
