In analyzing hits by certain bombs in a war, an area was partitioned into 579 regions, each with an area of 0.25 km . A total of 505 bombs hit the combined area of 579 regions. Assume that we want to find the probability that a randomly selected region had exactly four hits. In applying the Poisson probability distribution formula, u . e -H P(x) = x! identify the values of u, x, and e. Also, briefly describe what each of those symbols represents. . . . Identify the values of u, x, and e. H= , x= , and e = (Type integers or decimals rounded to five decimal places as needed.)
