利用随机数模拟10000个人的年龄和性别,以5年为一个年龄段对年龄和性别进行统计,给出统计结果(for和if...else语句的使用)

下面给出随机数的生成过程:
Random ran=new Randow();
ran.Next(max Value);//生成不大于 max Value值的非负整数
ran.Next(min Value,max Value);//生成介于min Value值 和 max Value值之间的一个整数

请教大家

顶一下,会的朋友帮帮忙吧

static void Main(string[] args)
        {
            int[][] arr = new int[1000][];
            for (int i = 0; i < arr.Length; i++)
            {
                arr[i] = new int[2];
            }

            Random ran = new Random();
            for (int j = 0; j < arr.Length; j++)
            {
                arr[j][0] = ran.Next(1, 120);
                arr[j][1] = ran.Next(0,2);
            }
            int sum1 = 0;
            int sum2 = 0;
            for (int j = 0; j < arr.Length; j++)
            {
                if (arr[j][0] >= 0 && arr[j][0] <= 5)
                {
                    sum1++;
                    if (arr[j][1] ==0)
                    {
                        sum2++;
                    }
                  
                }
               
            }
            Console.WriteLine("0~5岁的人数为：{0}男性为：{1} ", sum1, sum2);
}

感觉运算时间有点久
各位大虾看看能不能优化

楼主 如果老师给出答案你记得要发上来啊
