Using function NextRand(), we can generate random integers that range uniformly between 1 (inclusive) and N (inclusive), for an arbitrary positive integer N.int function randomInt(int N) {return 1+ int(N*NextRand());}

Using function NextRand(), we can generate a Boolean function that returns true with a given probability (and false otherwise); the following function returns true with probability p.bool function randomBool(float p) {return (NextRand() <= p);}

Using function randomBool(), we can generate a Boolean function that returns true, on average, once every N times that it is called.bool function randomEvent(int N) {return (randomBool(1.0/N));}
