Extracted text: 2. During the flu season, the probability that someone is sick is 0.3. Looking at 6 randomly chosen people: What is the probability that there are 2 or 3 persons who are sick out of 6 randomly chosen people? (Assume the event of being sick is independent across people.) a. Write out the probability distribution table b. What is the probability that there are 2 people sick? c. What is the probability that there are 2 or 3 people who are sick? d. What is the expected value? What if 20 people were randomly chosen. Would the expected value go up or down? Explain your answer. 3. Given that there is an 90% probability that a randomly selected adult knows what Twitter is, find the probability that when 5 adults are randomly selected, exactly 4 of them know what Twitter is. What is the probability that at least 4 of them know what Twitter is?
