1. A recent survey indicated that indicated that 80% of American COVID-19 patients only had mild symptoms. Suppose 4 American COVID-19 patients were selected at random. a) Last week, how did we compute the probability that exactly 3 patients had mild symptoms? b) How would we compute the probability of at least 3 had mild symptoms? This is not too difficult for a sample of 4 Americans. Larger samples could become more tedious. Let's explore... Question General Case Our example Is the number of trials finite? Are there two possible outcomes? Are the events independent? Is the probability that we're interested in constant from trial to trial? If all of these items hold true, then we have a Binomial Distribution (n, p, x)
