Given that ,
p = 0.5
n = 13
P(Fewer than 4)
= BINOM.DIST(4,13,0.5,TRUE) [Excel formula]
= 0.1334

A student takes an exam containing 12 true or false questions. If a student randomly guesses on the entire exam, what is the expected value of the number of incorrect answers? Do not round your answer.
A student takes a ten-question true-false quiz, but did not study and randomly guesses each answer. Find the probability that the student passes the quiz with a grade of at least 40% of the questions correct. (Round your answer to three decimal places.)
A student takes a ten-question true-false quiz, but did not study and randomly guesses each answer. Find the probability that the student passes the quiz with a grade of at least 60% of the questions correct. (Round your answer to three decimal places.)
A student takes a true-false test consisting of 15 questions. Assume that the student guesses at each question and find the probability that a. the student gets at least one question correct. b. the student gets a 80 % or better on the exam.
