Let X be the number of correctly answered questions
X ~ Binomial ( 10,0.2)
a) All questions are correct, X = 10
b) All Questions are incorrect , X = 0
c)
The Calculation table for prbabilities are given below using the Excel Command
=BINOM.DIST(x,10,0.2,FALSE)
x | P(X=x) |
1 | 0.268435 |

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.) (a) What is the probability that he will answer all questions correctly? (b) What is the probability that he will answer all questions...

Richard has been given a 7-question multiple-choice quiz in his history class. Each question has three answers, of which only one is correct. Since Richard has not attended the class recently, he doesn't know any of the answers. Assuming that Richard guesses on all 7 questions, find the probability that he will answer no more than 4 questions correctly. Round your answer to the nearest thousandth. Select one: a. 0.19 b. 0.128 c. 0.571 d. 0.5 e. 0.955
Richard has been given a 12-question multiple-choice quiz in his history class. Each question has four answers, of which only one is correct. Since Richard has not attended the class recently, he doesn’t know any of the answers. The success occurs if Richard answers a question correctly and the failure occurs if Richard is unable to answer a question correctly. Assuming that Richard guesses on all 12 questions, find the probability that he will answer no more than 3 questions...
A multiple-choice exam offers five choices for each question. Jason just guesses the answers, so he has probability 1/5 of getting any one answer right. One of your math major friends tells you that the assignment of probabilities to the number of questions Jason gets right out of 10 is (rounded to three decimal places):What is the expected number of right answers Jason will get if the test has 10 questions? A) 5 B)2.282 C) 2.493 D) 3.5 E)Can't tell...
