A two-way frequency table is shown below that displays the relationship between age and preferred vacation destination. We took a sample of 100 people and recorded the following results:
 

                      Disney World   Las Vegas    Alaska Cruise    Total

10–25 years            23                4                       3                30

26–40 years            8                 21                     5                 34

41–55 years           11                12                    13                 36

     Total                  42                37                     21               100



What is the probability (rounded to the nearest whole percent) that a randomly selected person is 41 to 55 years old or prefers vacationing in Las Vegas?
