Question 844086: I am having difficulty knowing what probability formula to use to solve word problems, any suggestions would be greatly appreciated. The following is an example of question I am trying to answer
It was found that 60 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. Forty percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2,000 years. Thirty 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? Thank You for any help!

Hi,

As I am understanding It:

Beijing 60%

Xi'am  40%

Both 30%

 (60%-30%) + (40%-30%) + 30%   0r  70% visit at least one
