Best ResponseYou've already chosen the best response.1The probability that it is a tuna sandwich is found by dividing the probability of a tuna sandwich by the sum of the probabilities of all the nonvegetarian sandwiches: \[\large P(tuna)=\frac{0.0658}{0.0711+0.0689+0.0569+0.0658}=you\ can\ calculate\]
