Question

Write a Java Program which includes at least 6 different questions with 4 Multiple Choice Options. Ask the User to choose one answer from those 4 choices. After answering all the answers by the user, your program should be able to compare user answers with the already saved correct answers and show the percentage of the total correct answers.

a. True
b. False

Answer 1

To find the probability that the student guesses more than 75 percent of the questions correctly, we need to consider each question individually and use the binomial distribution formula.

Step-by-step explanation:

Probability of Guessing Correctly

To find the probability that the student guesses more than 75 percent of the questions correctly, we need to consider each question individually. Since there are three choices for each question, the probability of guessing the correct answer is 1/3. Therefore, the probability of guessing more than 75 percent of the questions correctly can be calculated using the binomial distribution formula:

P(X > (0.75∗32)) = 1 - P(X ≤ (0.75∗32))

where X follows a binomial distribution with n = 32 and p = 1/3.
