Recently, a nurse commented that when a patient calls the medical advice line claiming to have th flu, the chance that he or she truly has the flu (and not just a nasty cold) is only about 10%. Of the next 23 patients calling in claiming to have the flu, we are interested in how many actually have th flu. Find the probability that exactly 4 of the 23 patients actually have the flu. Find the probability that fewer than 5 of the 23 patients actually have the flu. Find the mean of the distribution. Find the standard deviation of the distribution.
