Logo A Logo B Total Students 14 86 100 Teachers 14 11 25 Total 28 97 125 Are being a student and preferring logo B independent events? Why or why not?

Transcribed Image Text:Are being a student and preferring logo B independent events? Why or why not? OA. Yes, they are independent, because P(student) = 0.8 and P(student logo B) - 0.89. O B. No, they are not independent, because P(student) = 0.8 and P(student| logo B) - 0.78. %3D OC. No, they are not independent, because P(student) = 0.8 and P(student| logo B) = 0.89. D. Yes, they are independent, because P(student) = 0.8 and P(student logo B) = 0.78.
