(Original subject line: I just tried "question bank" and on one question, 4 out of 5 were the same question. Did I do something wrong?)
I set up a final exam with three question banks of three questions each. The first two were fine, but of the five completed finals thus far, four have the same question chosen for the third question bank. Do I just have a bad case of gambler's fallacy going on, or is this something others have experienced as well? It just doesn't seem very random.
