In Exercise 1 "Notation" we noted that in analyzing hits by V-1 buzz bombs in World War II, South London was partitioned into 576 regions, each with an area of 0.25 km2. A total of 535 bombs hit the combined area of 576 regions.
a. Find the probability that a randomly selected region had exactly 2 hits.
b. Among the 576 regions, find the expected number of regions with exactly 2 hits.
c. How does the result from part (b) compare to this actual result: There were 93 regions that had exactly 2 hits?
