Every question which we can answer is answered with a unique answer.
Solutions are contradictory.
For every one who sees clearly that a stock share should be sold, there is another one to whom it is obvious that the shares should be bought. For every Pro there is a Con. Computer power is so great now so that one can fumble around for a solution and still rapidly complete the process. Probabilistic situations are non-deterministic. But physicists have converted those problems to deterministic ones by restricting answers to descriptions of the range and frequency of those results.
