Answer:

No, they are not independent because P(student)= 0.87 and P(student/shark)=0.95

Step-by-step explanation:

Just took the quiz on Apex :)

The true statement about the events is (b) No, they are not independent because P(student)= 0.87 and P(student/shark)=0.95

How to determine the true statement?

Two events A and B are independent if

P(A∣B) = P(A)

Using the data entries in the table, we have:

P(Student) = 100/115

P(Student) = 0.87

Also, we have:

P(Student | Shark) = 90/95

P(Student | Shark) = 0.95

The probability values are not equal

i.e.

P(Student) ≠ P(Student | Shark)

Hence, the events A and B are not independent events because P(student)= 0.87 and P(student/shark)=0.95
