We use the Multiplication Rule for Probability when we are selecting more than one item and we make our selections one at a time.

Two Selections:  B happens first and A happens second.

Since we are selecting items one at a time, an important concept to determine before we start a problem is whether our selections are with replacement or without replacement. I typicaly start this lecture with a bag of marble example. The problem will go somewhat like this.
