第六章第三十二题（游戏：赢取双骰子赌博游戏的机会）(Game: chance of winning at craps)

**6.32（游戏：赢取双骰子赌博游戏的机会）修改编程练习题6.30使该程序运行10000次，然后显示赢得游戏的次数

**6.32(Game: chance of winning at craps)Revise Exercise 6.30 to run it 15,000 times and display the number of winning games.

下面是参考答案代码:

            }
        }
        System.out.println(count);
    }

    public static int random(int guess) {
        return 1 + (int) (Math.random() * guess + 1);
    }
}
