...problem multiple choice quiz? with the options being a,b,c,d and e would get a 100% of the questions correct?
Hope Kelly: This is a hypothetical mathematics question...aren't you a friken genius.. I'm going to give you best answer just so you can see my insult
 
Ok. I'm just gonna say that guessing isn't the best way to go on every problem. But if you're completely stuck, you could probably guess on one or two problems.
 
There is a 1 in 5 chance of getting each question right, so the answer is

(1/5) ^ 10

or 1 in 9,765,625
 
Since it goes to e, it would be (1/5)^10
This is because each question you have a 1/5 chance of being right,
so you raise 1/5 to whatever number of questions there are.
It would be 1/9765625.
Wow, that is not a very good odds.
 
(1/4)^10
because each answer has a 1/4 chance of being right, that probability times itself for each question on the quiz.
