    the answer is 4

    Look at the results

    TT,TF,TI, FT,FF,FI, IT,IF,II

    where T is a correct answer

    no look at the question very carefully ..

    What is the probability of exactly one correct answer?

    So that leaves these

    TT,TF,TI, FT,FF,FI, IT,IF,II

    Four.
    Exactly the same way I did it. Does this mean I am Tay?

        One part of a quiz consists of 2 multiple-choice questions with the suggested answers
        1. True
        2. False
        3. Insufficient Data to answer question.

        A student randomly marks one of the 3 answers to each question.

        What is the probability of exactly one correct answer?
        I've got the whole exam paper here:

        You may answer the following two questions by selecting True, False or Insufficient data.

        1. You have 4/9 chance of getting one one of these two answers right
        2. The answer to this question is false.

          Erm, I don't wish to appear pedantic(no more than usual anyway), but the above are two statements, not questions.

          ?

                Also, please state whether this statement is a question. (Answer True, False, or Insufficient Data).

                  It's about 4.86%.

                    Well, if we analyse your post...

                    With the lack of a question mark at the end of the text I would infer a statement. However, your use of the "Is" at the beginning of the text supposes a question.

                    In the end, it's all bollocks anyway.

                    That's why I like the Spanish language, not because of the bollocks, but because of the upside down question mark at the beginning of a question.

                      I didn't know the Spanish did that. Your point raises a 'question mark' over whether multiple choice papers should contain multiple choice statements or multiple choice questions though

                      Yeah, natural languages is bollocks, it's what makes them rich, carp, powerful, weak, and ambiguous. Humans especially love the ambiguity, or jokes as we sometimes call it. That wasn't one incidentally, because you aren't laughing Ambiguity is also lacking in multiple questions/statements requiring (True/False) answers, hence why they are not funny. So why isn't sasGurus question funny? (It has a 'insufficient Data' option). Maybe because a joke is funnier presented as a statement rather than a question
