If sample information is obtained, the result of the sample information will be either positive or negative report. No matter which result occurs, the choice to select option A or option B exists. And no matter which option is chosen, the eventual outcome will be good or poor. We know that P(good)=0.7 and P(poor)=0.3. Also, we know P( positive|good )=0.8, and P( positive|poor )=0.1. Please find the values of all posterior probabilities (in total there are 4 of them, for example P(good | negative)), and P(receive a positive report) and P( receive a negative report). Please show details of how you get the value.

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?
