Let e be the event that the student is blond, and let f be the event that the student is a junior. are events e and f independent? p(e|f) = % p(e) = % events e and f are .

E and F are independent.

Step-by-step explanation:

We are given two events. They are E and F

E is the event that the student is blond. (i.e. the student has pale or yellow hair)

F is the event that the student is junior.

We have to check whether E and F are independent.

Here probabilities are not given.  Hence we discuss logically.

A person having blond hair is nothing to do with his posiiton junior or senior in college.

In other words, the hair colour has no control over a student being junior.

In statistical terms, this can be interpreted as E and F are not dependent on each other.

Hence E and F are independent.

P (E|F) = 60%

P (E) = 60%

Events E & F are independent :)
