👉 In mathematics, a preguess is a method used in probability theory to generate random numbers. It involves generating two independent random variables, X and Y, where each variable has a uniform distribution on [0, 1]. The goal of the process is to find a value for Y that maximizes the product of X and Y. For example, if we want to generate a random number between 0 and 1 with a uniform distribution on [0, 1], we can use the following
