• 
  
  the strategies between 45 and 67 are dominated strategies.
  选择45至67之间的数并不是劣势策略
• 
  
  But it is the case that they're dominated
  但一旦我们剔除了原劣势策略
• 
  
  once we delete the dominated strategies:
  即选择67及大于67的数之后
• 
  
  once we delete 67 and above.
  他们才是劣势策略
• 
  
  So these strategies --
  所以这些策略
• 
  
  let's be careful here with the word weakly here --
  对于这里的弱一词 我们要谨慎对待
• 
  
  these strategies are not weakly dominated in the original game.
  这些策略在原博弈中并不是弱劣势的
• 
  
  But they are dominated
  可是一旦我们排除掉了68至100的数
• 
  
  they're weakly dominated
  他们就成为了劣势的策略
• 
  
  once we delete 68 through 100.
  即弱劣势策略
• 
  
  So all of the strategies 45 through 67, are gone now.
  至此所有45到67的数也被剔除了
• 
  
  So okay, let's have a look. Did anyone choose --
  好的 我们看一看 有人选了吗
