A literature professor decides to give a 15 question true- false quiz. If a student takes this quiz just by blind guessing, what the probability that he/she could get exactly 10 answers correctly?
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.)
An unprepared student makes random guesses for the ten true-false questions on a quiz. Find the probability that there is at least one correct answer.Could some one please help me?And explain to me how they got the answer?and is there another way besides the tree method?
A short quiz has two true-false questions and one multiple-choice question with four possible answers. A student guesses at each question. Assuming the choices are all equally likely and the questions are independent of each other, the following is the probability distribution of the number of answers guessed correctly. What is the Probability of getting less than all three right? X 0 1 2 3 P(X) .1875 .4375 .3125 .0625 Group of answer choices a) 1.0000 b) .9375 c) .6250 d) .3125
A test consists of 10 true/false questions. To pass the test a student must answer at least 6 questions correctly. If a student guesses on each question, what is the probability that: a. the student will pass the test b. the student will fail the test c. the student will get a 100 (all questions will be answered correctly)
A quiz consists of 30 true or false questions. If the student guesses on each question, what is the mean number of correct answers? A.) 0 B.) 15 C.) 6 D.) 30
Richard has just been given a 10-question multiple-choice quiz in his history class. Each question has four answers, of which only one is correct. Since Richard has not attended class recently, he doesn't know any of the answers. Assuming that Richard guesses on all ten questions, find the indicated probabilities. (Round your answers to three decimal places.) What is the probability that he will answer all the questions correctly the answer is 0.000 My question is how did they get...
A teacher gives an unannounced, three-question true false pop quiz, with two possible answers to each question. Complete parts (a)-(C) below. 2.
