A multiple-choice test consists of 6 questions. Each question has answer choices of a, b, c, and d, and only one of the choices is correct. If a student randomly guesses on each question, what is the probability that she gets fewer than 3 of them correct? Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.
