As an expert in mountaineering history and statistics, I can provide you with an informed answer regarding the number of fatalities on Mount Everest. It's important to note that the exact number of deaths can vary slightly depending on the source and the time the data is collected, as new incidents may occur and records may be updated.

Mount Everest, the highest peak in the world, has claimed the lives of many climbers over the years. The Himalayan Database, which is considered one of the most comprehensive sources for information on Himalayan mountaineering, reports that as of my last update, the number of fatalities stood at approximately 300. This number includes both climbers and high-altitude workers, such as Sherpas.

Fatalities on Everest can occur for a variety of reasons, including altitude sickness, weather-related issues, falls, and avalanches. The mountain's extreme conditions and the physical and mental challenges it presents make it a dangerous place, even for the most experienced climbers.

It's also worth mentioning that the number of deaths is a fraction of the total number of climbers who have attempted to summit Everest. While the risk is real, many climbers do reach the summit successfully.
