### Analysis of Fatal Crashes in 2016: Light and Weather Conditions

This section presents data on the number of drivers involved in fatal crashes in the year 2016, categorized by light and weather conditions. The information is sourced from the Fatality Analysis Reporting System.

#### Table: Fatal Crashes by Light and Weather Conditions

| Weather  | \ Daylight \ |  Dark, but Lighted | \ Dark \ | \ Dawn/Dusk \ | \ Other \ |
|------------|--------------|----------------------|--------|---------------|-----------|
| Normal     | 12,307       | 5,875                | 8,151  | 1,183         | 65        |
| Rain       | 875          | 497                  | 681    | 87            | 8         |
| Snow/Sleet | 219          | 51                   | 156    | 17            | 2         |
| Other      | 125          | 54                   | 220    | 40            | 9         |
| Unknown    | 810          | 255                  | 548    | 71            | 133       |

#### Questions for Analysis

a) **Determine the probability that a randomly selected fatal crash occurred in normal weather.**

b) **Determine the probability that a randomly selected fatal crash occurred in daylight.**

c) **Determine the probability that a randomly selected fatal crash occurred in rain or in dark, but lighted. Is this unusual?**

d) **Determine the probability that a randomly selected fatal crash occurred in normal weather or in daylight.**

e) **Would it be unusual for a fatal crash to occur while it is dark and raining? Include all dark conditions.**

### Explanation of Findings

To answer these questions, a detailed look at the provided table is necessary. For instance, to find the probability of an event, the relevant number of occurrences will be divided by the total number of occurrences across all conditions. The evaluation of unusual occurrences would typically be based on comparative probabilities or additional statistical methods.

### Graphical Representation

There are no explicit graphical representations in the provided image. However, summarizing the table data into bar graphs or pie charts could offer a visual understanding of the distribution of fatal crashes under various conditions.

### Important Note

When studying such data, it’s crucial to understand the context and impact of various conditions on traffic safety and
