Since the question is asking for the relative frequencies of the columns, we assume each row must add to 1.00. Divide the numbers in each row by the total of that row.
.. group 1, column A = 102/(102 +34) = 0.75
.. group 1, column B = 34/(102 +34) = 0.25
.. group 2, column A = 18/(18 +14) ≈ 0.56
.. group 2, column B = 14/(18 +14) ≈ 0.44
