在所有掷出的骰子的总和第一次成为素数之前,六面骰子的掷数是多少?我们计算这个随机变量的期望值和方差,直到加性误差小于。这是一个解决方案的难题提出的达斯古普塔在公报的研究所的数理统计,其中公布的解决方案是不完整的。证明很简单,结合了基本的动态规划算法和快速的Matlab计算以及有关素数分布的基本事实。
What is the number of rolls of fair six-sided dice until the first time the total sum of all rolls is a prime? We compute the expectation and the variance of this random variable up to an additive error of less than. This is a solution to a puzzle suggested by DasGupta in the Bulletin of the Institute of Mathematical Statistics, where the published solution is incomplete. The proof is simple, combining a basic dynamic programming algorithm with a quick Matlab computation and basic facts about the distribution of primes.
