A box contains 3 marbles: 1 red, 1 green, and 1 blue. Consider an experiment that consists of taking 1 marble from the box and then replacing it in the box and drawing a second marble from the box. Describe the sample space. Repeat when the second marble is drawn without replacing the first marble.

**Describe the sample space**

The sample space is all possible outcomes *with replacement*

$$\{ (R,R),(R,G),(R,B),(G,G),(G,R),(G,B),(B,B),(B,R),(B,G)\}$$

The sample space of all possible outcomes *without replacement*

$$\{ (R,G),(R,B),(G,R),(G,B),(B,R),(B,G)\}$$

Surround your text in `*italics*`

or `**bold**`

, to write a math equation use, for example, `$x^2+2x+1=0$`

or `$$\beta^2-1=0$$`
