    There are 32 possible cases.  5 will have 4 correct answers and 1 will have 5 correct answers.  Since the probability of getting a question wrong is the same probability as getting it right, then it's a wash and we can just divide the number of cases we're looking for by the possible number of cases

    6/32 =>

    3/16 =>

    0.1875

    18.75% chance of passing, if you answer questions randomly.

      If you don't want to help. Don't do it nobody is forcing you. Reserve your comments. You don't even know if I am studying.

    Probability of answering question#1 correctly = P(1) = 1/2

    Probability of answering 4 questions correctly = P(1)•P(2)•P(3)•P(4)

    ....................= 1/2•1/2•1/2•1/2

    ....................= 1/16

    ....................= 0.0625................ANS
