Kaolin is taking a multiple choice math test. Each question has seven presented answers, but only one is correct. If Kaolin guesses randomly for each of the nineteen questions the test has, determine the probability that Kaolin gets at most one question correct. A. 618719 B. 25719 C. (190) +(191)719 D 61825719 E. (61)(191)719

Suppose 12% of people prefer the look of LCD screens to MicroLED screens. If 2 people are randomly selected (assume independence), determine the probability that the first person or second person prefers LCD screens, i.e. find P(L1 or L2) A. 0.226 B. 0.088 C. 0.122 D. 0.156 E. 0.240

Multiple-choice questions each have five possible answers ( a, b, c, d )​, one of which is correct. Assume that you guess the answers to three such questions. a. Use the multiplication rule to find ​P(CWC​), where C denotes a correct answer and W denotes a wrong answer. b. Beginning with CWC​ ,make a complete list of the different possible arrangements of two correct answers and one wrong answer ,then find the probability for each entry in the list. P(CWC​)= ​P(WCC​)= ​P(CCW)=   c. Based on the preceding​ results, what is the probability of getting exactly two correct answers when three guesses are​ made?
