Answer 2

Answer:

Being a student and preferring “shark” are not independent events

Step-by-step explanation:

Let A be the event that the selected person is a student and B the event that person prefers sharks.

Total number of students =100

Hence P(A) =$\frac{100}{115} =0.8696$

P(B) = Persons who prefers sharks /total persons

=$\frac{95}{115} =0.8261$

P(AB) = no of persons who are students and who prefer sharks/total persons

= $\frac{90}{115} =0.7826$

P(A)P(B) = $=0.8696*0.8261\\\\=0.7183$

Since P(AB) does not equal P(A) P(B), we find that

A and B are not independent.

Being a student and preferring “shark” are not independent events
