2. Suppose your school is in the midst of a flu epidemic. The probability that a randomly-selected student has the flu is 0.15,
and the probability that a student who has the flu also has a
high fever is 0.90. But there are other illnesses making the
rounds, and the probability that a student who doesn't have the
flu does have a high fever (as a result of some other ailment) is
0.10.

Walgreens sells both kleenex and nyquil. in a random sample of 5000 purchases, it was found that 1200 contained kleenex and 540 contained nyquil. these are not independent because sick people are more likely to buy both and healthy people more likely to buy neither. in looking into that, it was found that 360 purchases contained both. a. make a two-way table to display this information. fill in the table with the missing entries, and be sure your table has row and column totals. b. if we randomly select a purchase that contained kleenex, what is the probability it also contained nyquil? c. what percent of all purchases didn’t contain either product?
