It was found that 61 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. 33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years. 18 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

0.76 = 76% probability that a tourist visited at least one of these places

Step-by-step explanation:

I am going to solve this question using the probabilities as Venn sets.

We have that:

Event A: Tourist visited Beinjing.

Event B: Tourist visited Xi'an.

61 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.

This means that

33 percent visited Xi'an with its magnificent terracotta soldiers, horses, and chariots, which lay buried for over 2000 years.

This means that

18 percent of the tourists went to both Beijing and Xi'an.

This means that

What is the probability that a tourist visited at least one of these places?

This is

We already found these values. So

0.76 = 76% probability that a tourist visited at least one of these places

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
