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?

visited museum didn't visit museum

visited zoo 9 14

didn't visit zoo 5 2

write the probability as a percent. round to the nearest tenth if needed.

Given:

                             visited museum           didn't visit museum      Total

visited zoo                      9                                     14                           23

didn't visit zoo               5                                        2                              7

Total                             14                                     16                           30

Simply look at the table and check the number that corresponds to visitors who visited the museum but did not visit the zoo. The number is 5. 
Divide it by the total number of people surveyed. Total is 30.

Probability visited the museum but did not visit the zoo = 5/30 = 0.16666 or 16.67%

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
