tell me what it is gonna be? 1, or 2, or 6, what make you think it is deterministic? Do you know how much money has been spent to study the ballistics, and everyone with a common sense knows that there is no 100% accuracy to shoot a bullet? rolling a dice cannot generate new knowledge? Have you ever heard randomized algorithm? Do you know that by applying a dice rolling, a randomized quicksort perform much better than deterministic quicksort? By rolling a dice, meaning chosing a random number, you can make cell phone call? without it you cell phone won't work? Do you know without using random number generator, there is no way to away network collision? Are these the knowledge you refering to? Or what do you mean by knowledge?
