Question

1. The following table gives the number of patrons of a local restaurant during each day of the week. Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday Number of Patrons 276 24% 233 309 291 340 342 Total: 2040 a. b. c. What is the probability that a randomly selected patron ate at the restaurant on Monday? What is the probability that a randomly selected patron did not at the restaurant on Friday? What is the probability that a randomly selected patron ate at the restaurant on the weekend (Saturday or Sunday)?

Explanation / Answer

The probability that a randomly selected patron ate at the restaurant on Monday = 249/2040 = 0.12

The probability that a randomly selected patron did not ate at the restaurant on Friday                        

                                               =(2040-340)/2040 =0.83

The probability that a randomly selected patron ate at the restaurant on weekend = (342+276)/2040

                                                                                                                      = 0.30
