Two six-sided number cubes are rolled. Each number cube has sides numbered 1 through 6. What is the probability that the outcome of the roll is a sum that is a multiple of 6 or a sum that is a multiple of 4?

This is the concept of probability and statistics. Given that the cube has 6 sides, the probability space will be: x={1,2,3,4,5,6,} P(x)=1/6 When the two dice are tossed, the combination that will give us a sum that is multiple of 6 will be: {1,2},{2,1},{1,1} probability of obtaining this combination is: (1/6*1/6)+(1/6*1/6)+(1/6*1/6) =1/12 The combination that will give us a sum that is multiple of 4 is: {1,1},{2,2} Probability of obtaining this is: (1/6*1/6)+(1/6*1/6) =1/18 the probability that the sum will be a multiple of 6 or 4 will be: 1/12+1/18 =5/36
