Tourists from a tour bus were asked about places they visited during their stay in a city. The results are shown in the table. What is the probability that a randomly selected tourist visited the museum, given that the tourist did not visit the zoo? Use the table to calculate a conditional probability. Write the probability as a percent. Round to the nearest tenth if needed. Show all of you work!!
