A multiple-choice test consists of 7 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 he gets more than 1 of them correct?Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.(If necessary, consult a list of formulas.)
