**Probability Exercise**

The probability that an event will happen is given as \( P(E) = \frac{18}{31} \).

**Task:**

Find the probability that the event will not happen.

**Solution:**

The probability that the event will not happen is calculated using the formula:

\[ P(\text{not } E) = 1 - P(E) \]

Where \( P(E) \) is the probability that the event will happen. Substituting the given value:

\[ P(\text{not } E) = 1 - \frac{18}{31} \]

Simplify and express the answer as an integer or a simplified fraction.

**Note:**

You have a time limit of 1 hour, 44 minutes, and 35 seconds to complete this task.

This activity helps in understanding basic probability concepts and operations.
