Question

It was found that 68 percent of the tourists to China visited the Forbidden City, the Temple of Heaven, the Great Wall, and other historical sites in or near Beijing. 61 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years. 29 percent of the tourists went to both Beijing and Xi'an. What is the probability that a tourist visited at least one of these places?

Expert Solution

Step 1

It is given that

P( Beijing ) = 68% = 0.68

P( Xi’an ) = 61% = 0.61

P( Beijing and Xi’an ) = 29% = 0.29
