    To prove that 2 events are independent you have to see that:

    P(A and B) = P(A)P(B)

    Re: How to show that events are independent?

    would you not be able to use conditional probability formula? I'm sorry if I sound really confused. I did some computing and I came to the conclusion that they are in fact dependent. Is this right?

    My argument was that:
    P(A|B)does not equal P(A) therefore they are dependent
