Final answer:
A filled-in triangle pointing downwards with a high number best represents a location with the greatest chance of precipitation.
Step-by-step explanation:
The station model with a high chance of precipitation typically includes specific symbols and numbers. One important symbol to note is a filled-in triangle pointing downwards, which represents precipitation. The size of the triangle indicates the intensity of the precipitation. Additionally, the number associated with the triangle indicates the probability of precipitation. For example, if the number is 50, it means there is a 50% chance of precipitation at that location. Therefore, the station model with a filled-in triangle and a high number (such as 80 or 90) would best represent a location with the greatest chance of precipitation.
