If I take a multiple choice test that has 30 questions with four possible choices as answers, and I need to answer 6 questions correctly to pass, what are the chances of my passing if I guess at all the answers? Or, for every 100 students who take it by guessing, how many could be expected to pass? Thanks. This is a real test administered by my state.

Sounds like it is pretty hard to fail that test. Realistically you have a good chance of selecting the minimum six correct answers randomly out of 30. And as far as the stats for a group of one hundred student, I am no statistician so I will leave that to someone else.
I will say, given the low passing requirements, the test cannot be too valid. But I do not know what the test is for, and why it is being given, so I can't really be the judge of that...can I?
Sounds to me like the point of the test is rather obvious and if the student cannot find 6 out of 30 correct answers to pass it, well maybe they shouldn't be there!

I think this is stupid because the odds are that you will randomly guess six of them right (well, really 7) right even without knowing anything.
