Pick a card from a standard deck, let A = heart Let B= king
P(A&B)= P(A)*P(B)
P(AB)= P(A) and P(BA) = P(A)
hope that helps

One of my students asked for an easy example to illustrate that when events are independent then P(A and B) = P(A)*P(B). He can follow the formulas and understands why the statement is true. He just wants an English example. Since I find most independence to be nonintuitive (except for obvious things like volcanic eruptions vs scores on AP exam), I was stuck.
