Calvin Stanton · Answer 1

Total number of persons that took this survey is 315+289+156+489 = 1249

To calculate required probability we need to divide number of males that cooked diner with the total number of persons in the survey.

315/1249 = 0.2522

If we round this to 2 decimals the answer is first option: 0.25
