A new virus, identified as Frost 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, X, will be a 1 if the person feeling sick does not live in Texas, a zero otherwise. The second variable, Y, will be a 1 if the person likes to eat icecream. A third variable, Z, will be a 1 if this person has been not been vaccinated against the virus. Your device will warn you of a possible virus transmission when the person answered no to the first question and yes to any of the other two questions. Design a Boolean expression representing your diagnostic (i.e. V = f(X,Y,Z), where V=1 implies a virus transmission warning.
