Answer

Explanation:

Step1: Calculate hockey yes & baseball yes

Total hockey watchers: 120. Subtract those who don't watch baseball: (120 - 70 = 50).

Step2: Calculate hockey no & baseball no

Total non-hockey watchers: 150. Subtract those who watch baseball: (150 - 60 = 90).

Step3: Compute row totals

Hockey yes total: 120 (given). Hockey no total: 150 (given).

Step4: Compute column totals

Baseball yes: (50 + 60 = 110). Baseball no: (70 + 90 = 160).

Step5: Compute grand total

Sum of row totals: (120 + 150 = 270).

Answer:

Baseball Yes Baseball No Total
Hockey Yes 50 70 120
Hockey No 60 90 150
Total 110 160 270
