Did I select the correct value from the contingency table for the events ? If not please correct and explain

Rows : Visit Columns : Preference 2' B Total 5 O 5 2 2 3 3 O 12 Total 6 3 20 Consider the probability experiment of randomly selecting one member of the population that you defined in the survey undertaken in Problem 1: -Let event A refer to the 1st value of the row variable being observed, which appears in the first row of the Contingency Table (i.e. this implies that P(A) = first row total divide by 20 etc..) Let event B refer to the 2nd value of the row variable being observed, which appears in the 2nd row of the Contingency Table --Let event C refer to the 3rd value of the row variable being observed, which appears in the 3rd row of the Contingency Table Let event D refer to the 1st value of the column variable being observed, which appears in the first column of the Contingency Table. -Let event E refer to the 2nd value of the column variable being observed, which appears in the 2nd column of the Contingency Table. Let event F refer to the 3rd value of the column variable being observed, which appears in the 3rd column of the Contingency Table
