What are the chances of that happening?

Apparently there is a bigger chance of the Earth being hit by an asteroid in 2014 than you or I winning the National Lottery well on any given ticket anyway. But statistically speaking, if indeed I have my sums right, you could increase your chances of winning to greater than Earth being hit by this asteroid by playing just twice a year before the asteroid is due to hit. And if you play every week you are therefore reducing the significance of the potential impact of this asteroid… no that can’t be right.

I’ve just given myself a headache.
