If the 1st drawn ticket is not replaced, the 2 events are negatively correlated.

If Event A occurs, the probability of Event B occuring drops.

If Event A does not occur, the probability of Event B increases.

An extreme case would be:

A = {first 3 tickets show odd number}

B = {next 3 tickets show odd number}

These 2 events are then called mutually exclusive events.

If the 1st drawn ticket is drawn and put back, then the 2 events are independent. The results of Event A has no bearing on Event B, and both could still happen, signified by P(AnB) = P(A)*P(B)
