Multiple-Choice Exam A student takes an 11-question, multiple-choice exam with four choices for each question and guesses on each question. Assume the variable is binomial, Part: 0/ 2 Part 1 of 2 Find the probability of guessing at least 7 out of 11 correctly. Round intermediate calculations and final answers to at least three decimal places. P(guessing at least 7 out of 11 correctly) = Part: 1/2 Part 2 of 2 Would you consider this event likely or unlikely to occur? Explain your answer.
