The faces of each of two fair dice are numbered 1,2,3,5,7, and 8. When the two dice are tossed, what is the probability that their sum will be an even number?两个标准骰子的 6个面都标有数字 1,2,3,5,7,8.当掷了这两个骰子,问它们的数字和是个偶数的概率是多少?
How to solve the problem: The probability of getting an odd number first is 46=23. In order to make the sum odd, we must select an even number next. The probability of getting an even number is 26=13. Now we multiply the two fractions: 23×13=29. However, this is not the answer...
