Nanalyzing hits by certain bombs in a war, an area was partitioned into 556 regions, each with an area of 0.15 km2. a total of 505 bombs hit the combined area of 556 regions. assume that we want to find the probability that a randomly selected region had exactly three hits. in applying the poisson probability distribution formula, p(x)equalsstartfraction mu superscript x baseline times e superscript negative mu over x exclamation mark endfraction , identify the values of mu, x, and e. also, briefly describe what each of those symbols represents. identify the values of mu, x, and e.
