    What question? There is no answer because there is no question. I may not always be correct, but I'm never wrong. ;-)

    100% is the highest% you can get... there are 4 options with each one being 25% since 25X4=100

    There is a 0% chance that you'll be correct.

    TimHathaway is correct that there's a 25% chance of picking any one particular answer. However, both A and D say "25%"; therefore, you'll randomly select "25%" as an answer 50% of the time. Clearly, therefore, 25% cannot be correct.

    Meanwhile, the 50% answer only appears once, so there's only a 25% chance that you'll choose it. Therefore, it too can be eliminated as the correct answer.

    Finally, 35% also only appear once, so it likewise will be chosen 25% of the time. Again, clearly not the correct answer.

    Thus, since none of the multiple choice answers are correct, you have a 0% chance of getting the correct answer.

    Yes but you have to consider that 25% is there twice.

    OK, you guys just lost me... I,thought it was 25%, but seeing there are 2 25's, I guess it could've been 50% also

    answer:
    33.33% isn't one of the available answers! Therefore, you can't possibly be correct 33.33% of the time.

    The answer is 0%.

    The key word is "randomly" therefore I would be correct every time I randomly choose. I Я SMART!
