C. Find the expected distance between two randomly
selected people in the
greater Camville-Bigton metropolitan area.

d. Find the expected distance between two randomly
selected people, one
from each town, assuming that one can cross the River Charlie at
*any* point along
the _{B}
miles of Bigton that run along the river. By how much does your
answer differ from your
answer in part (b) ?

e. Compute numerical values for all the
questions above assuming that

i. _{B}
= 4 miles
ii. _{B}
= 2,000 people/square mile

_{c}
= 6 miles
_{c}
= 1,000 peoplel/square mile

*u* = 2 miles

*v* = I mile

*W*_{B} = 5 miles

*W*_{c} = 3 miles
