WebbThe math.random function generates pseudo-random numbers. We can call it in three ways. When we call it without arguments, it returns a pseudo-random real number with uniform distribution in the interval [0,1). When we call it with only one argument, an integer n, it returns an integer pseudo-random number x such that 1 <= x <= n.
