# When taking a 7 question multiple choice test,where each question has 5 possible answers,it would be unusual to get ...........or more questions correctly by guessing alone?

It would be unusual to get 2 or more questions correct by guessing.

You have a 1 in 5 probability of guessing the correct answer for a single question. You have 7 opportunities to guess.

So guessing more than 1 question correctly with 7 total questions on the test (trials) would be unusual. Guessing correctly on at least 1 question would be expected.
