84% on a standard grading scale is a B. So you divide 84% by B's 50% again and get 168%.

But we can't forget 25% for D. 168% x 25% = 42%.

So yeah, trick question. The right answer is 42 which is none of the above.

OMG I love that

If you didn't know and just guessed you would have a 50% chance of answering the question correct. This is the same thing

i see what you're saying but the answer is not A or D the answer is B. therefore you don't have a 50% chance at random.

In that case yes. But in the question posed, only one answer is 50%. That means you only have a 1/4 chance of randomly (assuming random means answers A,B,C and D are equally likely to get picked) picking answer B. Since you only have a 25% chance of picking B, B cannot be correct.

It's a paradox, which means it has no solution.

The only way you can make this question solvable is to say that random means something else, for instance a random distribution where you have a 10% chance of picking A, a 20% chance of B, a 60% chance of picking C and a 15% chance of picking D. In that scenario, C would be the correct answer. But a situation like that is the only way this question is solvable.

None of the above

You have a 33.333% chance of guessing the right answer.

A&D - 25%
B - 50%
C - 60%

Even though there are 4 choices, 2 of them are the same answer, so really there are only 3 different answers to choose from.

The question has nothing to do with what the answers say other than the 2 that are the same (A & D), the numbers are there to confuse you. It has everything to do with the number of different answers you have to choose from.

There are 3 different answers ...25% 50% and 60% 100 / 3 = 33.333%

The answer is A and D, both answers are correct and thus 50% is the solution.

then your saying 50% is correct and A and D's answers of 25% are not correct. If you don't understand that then I'm done.

your logic is off bruh

there are contradictions. It's a paradox.

If I didn't cheat I would agree. This was an extra credit problem on a probability and statistics course I'm currently in

and 50% is the correct answer your professor/teacher gave you? What school is this?

OH HELL YES I LOVE A GOOD MATH FIGHT

you have a 2 out of 4 chance of picking it correct, 2/4 *100 = 50%

my god are people this stupid?

the answer is 33.333% NONE OF THE ABOVE
