# Question

Check in each case whether the values of n and θ satisfy the rule of thumb for a good approximation, an excellent approximation, or neither when we want to use the Poisson distribution to approximate binomial probabilities.

(a) n = 125 and θ = 0.10;

(b) n = 25 and θ = 0.04;

(c) n = 120 and θ = 0.05;

(d) n = 40 and θ = 0.06.

(a) n = 125 and θ = 0.10;

(b) n = 25 and θ = 0.04;

(c) n = 120 and θ = 0.05;

(d) n = 40 and θ = 0.06.
