Tomorrow, Sharon is going to sit for her mathematics test. The test paper consists 10 multiple choice questions with four possible answers A, B, C, and D for each question. Due to lack of practice, she is going to try her luck by guessing the correct answer for each question. Sharon needs to pass the test by getting at least five answers that are correct, but she is expecting correctly guessed five answers to pass the exam. a. Determine whether the possible answers A, B, C, and D are equally likely. b. Determine the total number of equally likely outcomes for all the questions. c. Define the event of interest for Sharon. d. Determine the number of outcomes with the event of interest for Sharon. e. Compute the classical probability using Equation 1.
