when analyzing hits by certain bombs in awar, an area was partitioned into 551

551 regions, each with an area of 0.25

0.25 km2. A total of 515

515 bombs hit the combined area of 551

551 regions. Assume that we want to find the probability that a randomly selected region had exactly two

two hits. In applying the Poisson probability distributionformula, P(x)equals

=StartFraction mu Superscript x Baseline times e Superscript negative mu Over x exclamation mark EndFraction

xex!, identify the values of mu

, x, and e

e. Also, briefly describe what each of those symbols represents.
