The probability of drawing two aces from a standard deck is 0.0059. We know this probability, but we don't know if the first card was replaced. If the two draws are defined as event A and event B, are the events dependent or independent?

    To answer the question we need to know if we replaced or not.

    Lets calculate the 2 probabilities.

    1, No replacement

    first draw is an ace P=4/52

    2nd draw is an ace P=3/51

    Both are A: P=4/52 * 3/51 = 0,0045

    2, With replacement

    Both draws P=4/52

    Both A: P = (4/52) ^2 = 0,0059

    So we know that it was with replacement.

    This means theat the two events are independent. (both draws have 4/52 chance, not affecting eachother)
