    Probability in true/false exam with -1 if wrong

    Hi!

    I'll gonna do a law exam in a few days, and I need your help
    The test is a 120 questions true/false, 1 point for each correct, and if your answer is wrong, you lose 1 point.
    If you leave it blank, you dont lose nothing.

    My question is: based in probability, what's the best option? Answer all that I dont know or leave it blank?

    THanks in advance and sorry for my English

    Hey Mercantigo.

    The best answer I could give when it involves probability is to think about what the probabilities are and consider that a higher probability is "more likely".

    Just remember though that since they are probabilities, a higher number doesn't mean that its true: just that it is more likely and if the probabilities are accurate, then you should use them as a guide.
