On a multiple choice test of 10 questions, each question has 5 possible answers. A student is certain of the answers to 4 questions but is totally baffled by 6 questions. If the student randomly guesses the answers to those 6 questions, what is the probability that the student will get a score of 5 or more on the test. Express your answer correct to 2 decimal places.
I really don't know how to work this out because of 10 questions 5 possible answers is a bit confusing
