If you know that each option (ABCD) is roughly 25% likely to occur, is it a better bet to guess all Cs (guaranteeing around 25%, probably a fail in most tests), guess 25% of each option randomly (so if there were 20 questions, 5 for each option), or do something in between?
Or what if you know that some option are more likely than others, let's say C has a higher chance of occurring than ABD. Should you go for all Cs or should you mix in some ABD?
And if you have already completed 50% (or any other amount) of the test already with presumably correct answers, is it better to guess all Cs for the ones you missed or to distribute them so that there are 25% ABCD each (or a different ratio if you know some are more likely on average)
edit: I'm not planning on random guessing every option on any future tests, and certainly not counting every option to ensure a spread out distribution (that would take up lots of time!). It's just a silly probability question
As someone building quizzes as part of my job, my strategy is usually to assign the correct answer to C or D by default, but then i would randomly change to the others options in an attempt to homogenize the answers. I definitely like using A more than B (not sure why)
Having said all that.... be careful if you're taking a quiz on Canvas or Blackboard, both offer the option to randomize the multiple choice answer list so the order is different for each person.
