【题目】T he Poisson distribution is a probability distribution for an event occurring times over a given interval. T he interval is usually a time interval, such as the number of people enteringa store during one hour. T he distribution is adiscrete distribution, so must be a whole number...
The Poisson distribution is a probability distribution for an event occurring x times over a given interval. The interval is usually a time interval, such as the number of people entering a store during one hour. The distribution is a discrete distribution, so x must be a whole number. The...
