When the occurrence of mineral (e.g. rare minerals) is randomly distributed in a rock then which of the distribution pattern is statistically followed?

Answer: Option D

In a Poisson distribution, the occurrence of events (in this case, the occurrence of minerals in a rock) is randomly distributed over a given interval. This distribution is commonly used to model rare events and is often used in mining engineering when studying the distribution of minerals in rocks. Therefore, the correct option is D.
