WebHere, the distribution parameter lambda is a scalar. Use the poissrnd function to generate random numbers from the Poisson distribution with the average rate 20. The function returns one number. r_scalar = poissrnd (20) r_scalar = 9. Generate a 2-by-3 array of random numbers from the same distribution by specifying the required array dimensions. WebThe cumulative Poisson probability table tells us that finding $P(X\le 3)=0.265$.
