This is certainly true. |

That is not as clear. Prob = 1 does not always mean certain (when there |
| 12 |
are infinite possibilities). For example the probability is zero that a |
| 13 |
random rational number chosen between 0 and 1 is exactly 1/2. So the |
| 14 |
probability is 1 that the number is not 1/2. However it is not certain |
| 15 |
that the random choice will not be 1/2. |
