To find the variance of a Poisson distribution, we can use the fact that the variance of a Poisson random variable is equal to its expected value.
In this case, the expected value of x is given as 3. Therefore, the variance of x is also equal to 3.
Answer:\text{Var}(x) = 3
In this case, the expected value of x is given as 3. Therefore, the variance of x is also equal to 3.
