The mathematical expression for the Poisson distribution is shown as P(x)= e⁻λλˣ/x! The term x stands for ______.
A)probability of arrivals
B)number of arrivals per unit of time
C)expected or average arrival rate
D)total arrival time

Question

Quizplus · Accepted Answer

The term x in the Poisson distribution represents the number of arrivals per unit of time. This distribution is used to calculate the probability of a certain number of events occurring in a fixed time interval, given the average or expected number of events (λ) in that interval. Therefore, x is the variable that represents the number of events or arrivals.
