A group of 120 people were asked whether their income level is above or below $25,000 and whether they subscribe to a movie channel. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table. A circle labeled below 25,000 dollars 55 overlaps a circle labeled subscriber 34. Overlap is 18. 4-column table with 3 rows. First column has no label with entries subscribes, does not subscribe, total. Second column is above 25,000 dollars with entries a, 13, 47. Third column is below 25,000 dollars with entries b, 55, 73. Fourth column is labeled total with entries 52, c, 120.
Which shows the correct values for the variables in the table?

a = 18, b = 34, c = 65
a = 34, b = 18, c = 68
a = 34, b = 68, c = 47
a = 47, b = 18, c = 68
