然而我只会这样

1. vip = 50
   
2. all = 0.0
   
3. lose = 0
   
4. loop do
   
5.   i = rand(6)+1
   
6.   if i > 2
   
7.     vip += 10
   
8.   else
   
9.     vip -= 10
   
10.   end
    
11.   if vip == 120
    
12.     all += 1
    
13.     vip = 50
    
14.   elsif vip == 0
    
15.     all += 1
    
16.     lose += 1
    
17.     vip = 50
    
18.   end
    
19.   if all == 100000
    
20.     break
    
21.   end
    
22. end
    
23. j = lose/all
    
24. p j
    
25. exit
