Kind of a vague question :/ Each guess is independent of every other guess, i don't think mutual exclusivity is relevant here.

Vague is right.

yttrium · Answer

what is the clearest difference bet ind and mut exclusive?

agent0smith · Answer

yep each guess is independent, but lol the question doesn't even specify. What is the event? each guess? the entire set of answers? Whether you spontaneously combust while guessing?

Mutually exclusive - the two events can not happen together

independent - one event occurring does not affect the probability of the other occurring

The randomly selected answer to any question has no effect on the choice of answer for other questions. Therefore the probable result of the test is determined by the probabilities of 30 independent events.
