   In order to understand more about the situation you should work out some   
   problems yourself. Here is one:   
      
    There are some random variables A, B, C. The probability that A and   
    B are different is p and the probability that B and C are different   
    is q. All probabilities are real numbers between 0 and 1.   
    This information is insufficient to determine the probability that A   
    and C are different but it allows to infer some limits to that   
    probability. What are those limits?   
      
   The result is not Bell's inequality but it can be used for similar   
   purposes. In particular, the result can be used instead of Bell's   
   inequality to show that no local hidden variable theory is equivalent   
   to quantum mechanics.
