  I meant to point to that.
  我还是指给大家看吧
• 
  
  20 with probability of 1-Q
  1-Q的概率获得收益20
• 
  
  So what?
  然后呢
• 
  
  So what is this:
  我们这么做的意思是
• 
  
  we're looking for a mixed strategy Nash Equilibrium,
  我们要寻找混合策略纳什均衡
• 
  
  so in particular, not only Serena is mixing
  实际上不仅仅塞丽娜混合了自己的策略
• 
  
  but in this case what we're claiming is, venus is mixing as well.
  我们也要知道维纳斯也在混合她的策略
• 
  
  So if Venus is mixing as well,
  如果维纳斯也混合了策略
• 
  
  that means that Venus is
  这就意味着
• 
  
  using the strategy left with some probability P
  维纳斯有P的概率选左
• 
  
  and using the strategy right with some probability 1-P.
  1-P的概率选右
• 
  
  Since Venus sometimes chooses left and sometimes chooses right
  由于维纳斯可能选左也可能选右
