What is \( \mathrm{P}( \) not even \( ) \) ? Write your answer as a fraction or whole number.

To find \( \mathrm{P}( \text{not even} ) \), we can consider the total probabilities of the outcomes in a given set and determine the likelihood of a result being "not even." Assuming we're dealing with rolling a fair six-sided die, the total outcomes are 1, 2, 3, 4, 5, and 6. The outcomes that are even are 2, 4, and 6. This gives us 3 even outcomes. Thus, there are 3 outcomes that are not even: 1, 3, and 5. The probability can be calculated as follows: \[ \mathrm{P}(\text{not even}) = \frac{\text{number of not even outcomes}}{\text{total number of outcomes}} = \frac{3}{6} = \frac{1}{2}. \] So, \( \mathrm{P}( \text{not even} ) = \frac{1}{2} \).
