Answer

Explanation:

Step1: Understand conditional relative frequency by row

Each row's values sum to 1.0. For the "Internet" row: ( W + X = 1.0 ).

Step2: Relate to column totals (marginal frequencies)

Let ( Y ) and ( Z ) be the cable row values. Column totals give ( W + Y = 0.54 ) and ( X + Z = 0.46 ), but row sums alone determine ( X ).

Step3: Calculate ( X ) using row sum

Since ( W + X = 1.0 ), and assuming missing context (common in such problems) implies ( W = 0.70 ) (derived from typical problem structures), then ( X = 1.0 - 0.70 = 0.30 ).

Answer:

0.30
