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

Answer:

0.25

Step-by-step explanation:

add all the possibilities up and divide them by (male that cooked dinner)

[tex]\frac{315}{1249} =0.2522017=0.25[/tex]
