Arrey, that's because one of the events has to happen, babu. If you add the chance of drawing every single ball in the bag, of course it'll be one – it's certain something comes out! Frankly, I should know this from trying to predict my weekend gigs. Calculating the probability of a full house, an empty hall, or a broken string – add those up, and it's a perfect, sad 'one' that I'll be playing no matter what.
