The Poisson distribution is a statistical model used to predict the number of events in a fixed interval. Its unique property is that the mean and variance are equal, both represented by λ. This distribution is versatile, applicable in fields like physics, finance, and biology, aiding in performance evaluation, resource optimization, and forecasting. Understanding its mean, variance, and standard deviation is crucial for data analysis and strategic decision-making.
