概率问题，小白求解
本帖最后由 Ddaniel1177 于 2021-9-12 18:30 编辑买彩票，然后问至少要买多少张才能至少中三个白球。
这是我目前的代码
import random
print("Buy a ticket with 5 white balls and 1 red ball ")
mywhite = random.sample(range(1, 69), 5)
myred = random.randint(1, 26)
white =
red = 1
print("Your selection for white balls are: ", *mywhite )
print("Your selection for red balls is: ", myred )
print("Winning numbers for white balls：", *white)
print("Winning number for red ball：", red)
matchwhite = 0
for i, j in zip(mywhite, white):
if i == j:
matchwhite += 1
matchred = 1 if myred == red else 0
if matchwhite == 0 and matchred ==0:
print ("No matching. Thanks for your contribution!")
elif matchred:
if matchwhite == 0:
print ("Matching only the red ball: $4")
elif matchwhite == 1:
print ("Matching the red ball and one white ball: $4")
elif matchwhite == 2:
print ("Matching the red ball and two white balls: $7")
elif matchwhite == 3:
print ("Matching the red ball and three white balls: $100")
elif matchwhite == 4:
print ("Matching the red ball and four white balls: $10,000")
else:
print ("Matching five white balls and the red ball: Jackpot")
else:
if matchwhite == 3:
print ("Matching three white balls: $7")
elif matchwhite == 4:
print ("Matching four white balls: $100")
else:
print ("Matching five white balls: $1,000,000")
求大佬能帮我解答一下，感激不尽！！ import random

print(count) 你該不會是想要用代碼運算答案去買樂透吧？{:5_94:}兄弟，這和你當初題目設定不一樣哦，那些沒有中獎的不用打印？只算出次數？{:5_94:}{:5_94:} 傻眼貓咪 发表于 2021-9-12 19:22

哈哈哈，这是一个题啊，只是附加的问题。
我如果想买彩票，我就会问全中该怎么算了{:10_250:} 傻眼貓咪 发表于 2021-9-12 19:22

大佬，为啥我把你代码的最后一段放进我的里面，它就开始一直循环啊。难道是要出现三次中3个白球的情况才停下来吗？有什么方法可以直接得出结果吗？ Ddaniel1177 发表于 2021-9-12 19:45

1. 用我的代碼就不會出現無限循環，你把我的後半段代碼放進別人的前半段代碼當然有問題咯，看來我的代碼並不是你想要的啊。{:5_99:}
2. 你用我的代碼你會發現，只求中獎三顆白球以上的機率不高啊，幸運可能 300 次以內，否則上千上萬次數，你確定全部結果要打印？
不好意思兄弟，我的 Python 技術不是很厲害，你的題目我無法解了，你看看有沒有其他大神可以幫助你 我运行了一下你的代码，但是为什么其它的都不显示，只显示一个次数啊 Ddaniel1177 发表于 2021-9-12 20:30

你上面要求中獎三顆白色球的次數啊，不是嗎？{:5_94:}
兄弟你先想清楚，你真正想要什麼，問題必須要有邏輯，有條有理，不然別人很難解決你的問題啊～
大家的代碼只是參考，你必須要了解其原理啊，然後試試自己動手寫吧
盲猜应该买 69*68*67 = 314364 张
