Assume everybody knows 649.
Q1: What is the probability such that the sum of a 649 outcome, i.e. sum
of 6 numbers, is divided by 6? 1/6 or not?
Q2: Given a number, say 50, is there are a number n, such that any n outcomes of 649, i.e. sum of 6*n numbers, is divided by 50?
BTW. I am a 649 fun. Some questions related to 649 bother me. Hope some smart guys here will help me.
