Math game: Dice game 1, title: Dice game 2, content: 1) Design two big math games with dice; 2
By analyzing the probability with the list method, the probability that the sum is 6 or 7 and the sum is other numbers is obtained respectively, so as to know whether the first game is fair or not; Find out the probability that sum is divisible by 3 and the probability that sum is divisible by 3 respectively, and then multiply it by the corresponding score to know whether game 2 is fair or not. 1, the list is as follows: From the table, we can know that the first game is unfair. Because, therefore, the second game was unfair. Change the second scene to "sum is divisible by 3, and Xiao Ming gets 2 points, otherwise Xiao Fang gets 1 point, which is fair. There is no only way to turn the game into a fair game. As long as Xiao Ming's score is twice that of Xiao Fang, the game is fair.
