Question

If mean for poisson distribution is equal to 4 then variance of exponential probability distribution is

Answer 1

exponential probability distribution is Poisson distribution
in passion distribution
mean=variance=4

Answer 2

Answer:

Varience = 4

Step-by-step explanation:

Poisson Distribution P(x,u)=(e ^ (- u))(x ^ x)x|

u -> mean

P(x = 1) = P(x = 2)

(e ^ (- u) * x ^ 2)/1! = (e ^ (- u) * u ^ 2)/2!

u = 4

Mean = 4

I Now, in case of Poisson distribution, the parameter, m but is not only the mean also the variance of the distribution.

variance =  u

Variance = 4

In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event.
