Solution

Solution Steps

Step 1: Identify the Parameters

The total number of observations (N) is 1232, and the number of instances where the event occurred (E) is 397.

Step 2: Apply the Probability Formula

The probability of the event occurring in a future instance is calculated using the formula: $$P = \frac{E}{N}$$ Substituting the given values, we get: $$P = \frac{397}{1232}$$

Step 3: Calculate the Probability

By performing the division, we find that the probability is 0.322.

Step 4: Round the Probability

Rounding the probability to 3 decimal places, we get 0.322.
