Define poisson probability distribution. Cars arrive at a petrol station at an average rate of 3 per minute. Assuming that the cars arrive at random, find the probability that (i) no car arrives during a particular minute. (ii) at least one car arrive during a particular minute. (iii) four cars arri
Define poisson probability distribution. Cars arrive at a petrol station at an average rate of 3 per minute. Assuming that the cars arrive at random, find the probability that (i) no car arrives during a particular minute. (ii) at least one car arrive during a particular minute. (iii) four cars arrives in any 2 minutes. [5]
The Poisson distribution is a discrete probability distribution that describes the number of events occurring in a fixed interval of time (or space), given that these events occur with a known constant average rate $\lambda$ and independently of each other. It is a limiting case of the binomial d...
