Hi,
 
Think of it this way:
 
What’s the probability of the opponent choosing a losing hand (rock, paper or scissors)?
 
Because there are only three possible outcomes with the same probability, they each are 1/3 = 0.33 probable to occur. The chance of you winning is the same as the probability of the opponent losing.

You must to answer this question.
