# Introduction to Probability Distribution

A Courtyard Hotel by Marriott conducted a survey of its guests. Sixty-two surveyors were completed. Based upon the data from the survey, (see attached) determine the following:

a) Two customers are selected. What is the probability that both will be on a business trip?

b) What is the probability that a customer will be on a business trip or will experience a hotel problem during a stay at the Courtyard?

c) What is the probability that a customer on business will have an in-state-area-code phone number?

d) Based on the data, can the Courtyard manager conclude that a customer's rating regarding staff attentiveness is independent of whether he or she is traveling on business, pleasure, or both? Use the rules of probability to make this determination?

a) Two customers are selected. What is the probability that both will be on a business trip?

According to the data provided among, there are 36 customers that are on a business trip. The probability that two of them will be on a business trip would be: (n=62, k=36)

Pa= (k/n) ...
