A new virus, identified as Bud virus, is beginning to spread in the USA. Scientists are trying to find a way to speed up the diagnostic of such a disease. Software companies are developing Apps that could be used in smart phones. You tried to look at the problem from a logical point of view and it seems that you found a way to describe the transmission of the disease with a simple Boolean expression. Your solution utilizes three input variables. The first one, A, will be an 1 if the person you are talking to has been recently in St. Louis, Missouri, a zero otherwise. The second variable, B, will be an 1 if the person went to a bar and drank some of their beers but cannot recall which ones. The third variable, C, will be a 1 if this person has been vaccinated against the virus. Your device will warn you of a possible virus transmission when the person answered yes to any of the two first questions and no to the vaccination. Design a Boolean expression representing your diagnostic (i.e. V = f(A,B,C), where V=1 implies a virus transmission warning.
