| rt2007 | what is sample space ? can anyone explain ? |
| bdoggprod | They are defining the sample space as all of the possible outcomes for the experiment. |
| TammTamm | Thanks AN for explaining stats the way it's taught in undergrad. It makes it easier to understand than the readings. |
| Kennyk11 | It should be noted that C is wrong because you can only pick one color and one side of the coin, since they are mutually exclusive (two events that cannot occur at the same time). |
