Let x be the number of tree seedlings in a randomly selected one square meter plot in a forest. Suppose that x has a Poisson distribution with λ = 5, which corresponds to an average of five seedlings per square meter. Find the probability that a randomly selected one square meter plot contains no seedlings.
