this is a tricky question alright.
i was initially confident of the B answer, posted my reply, had doubts. googled it, confirmed my initial thoughts, but i went on to devise a more logical approach (this is my own logic, not from net)
ok to start: question is
[Quote="Question posed by blackboard"]if you choose an answer to this question at random, what is the chance you will be correct.[/Quote]
now by including the wording "what is the chance you will be correct" this is a question about probabilities, therefore each possible outcome has to be examined to correctly determine the proper chance, which is the actual question.
now the logicaly tricky part is here,
to answer the question at random i can only pick 1 of a,b,c or d.
i have a 25% chance of randomly picking A (which gives answer 25%) and i have a 25% change of randomly picking D (which gives answer of 25%)
(the logical fallacy is that if i was to genuinely choose the answer a or d then it is wrong,
but the question doesn't ask this, it asks what are the Chances of picking the right answer, not what is the right anwser)
so now returning to the original question, randomly answering a or d is correct, therefore 50% of my options will give me the right answer.
