c# - 试图找到 Tom 在 : 10 repetitions 上掷出 6 所需的平均尝试次数

Question

它需要滚动的总数并将它们除以 10。例如，如果需要 56 个滚动，那么我的平均值是 5.6。

        Random numGen = new Random ();

        int numOfAttempt = 0;
        int Attempt = 0;
        int avrBefore = 0;
        int avrAfter = 0;


        for (int i = 1; i <= 10; i++)

            do {

                Attempt = numGen.Next (1, 7);
                Console.WriteLine (Attempt);
                numOfAttempt++;
                avrBefore = numOfAttempt;
                avrAfter = avrBefore / 10;

            } while (Attempt != 6); 

        Console.WriteLine ("He tried " + numOfAttempt + " times to roll a six.");
        Console.WriteLine ("The average number of times it took to get a six was " + avrAfter);
        Console.ReadKey ();

也许您需要在 while 之前重置 for 循环内的变量:

    for (int i = 1; i <= 10; i++){
    int numOfAttempt = 0;
    int Attempt = 0;
    int avrBefore = 0;
    int avrAfter = 0;

        do {//your code
