B)xx = 27,yy = 77 
C)xx = 27,yy = 79 
D)xx = 72,yy = 77

To solve for the missing values, we can use the formula for calculating the marginal totals. The marginal total for row 1 is 139 (79 + 60) and the marginal total for column 1 is 99 (27 + 72). To find the missing value in cell 1,1, we subtract the sum of the known values in row 1 (79) from the marginal total (139), giving us 60. Similarly, to find the missing value in cell 2,2, we subtract the sum of the known values in column 1 (27) from the marginal total (99), giving us 72. Therefore, xx = 27 and yy = 79, and the best choice is C.
