Suppose that at a shopping center with 1,050 shoppers, 550 arrived by car and 120 arrived by bus. Which of the following mathematical operations would result in the probability that a shopper picked from this group at random arrived either by car or bus? Select one: a. 550 1050 + 120 1050 5501050+1201050 b. ( 550 1050 )×( 120 1050 ) (5501050)×(1201050) c. 550 1050 + 120 1050 − (1050−550−120) 1050 5501050+1201050−(1050−550−120)1050 d. ( 550 1050 )×( 120 1050 )− (1050−550−120) 1050 (5501050)×(1201050)−(1050−550−120)1050
