Javascript Question

I've implemented the function:

`function coinFlip() {`

return(Math.floor(Math.random()*2) === 0) ? 'Heads' : 'Tails';

}

And it's all working fine (I already tested it).

My problem is, how do I make this function so that the probability of getting 'Heads' is 30% while the probability of getting 'Tails' is 70%?

Thanks in advance
