One thousand adults live in Milltown. Every day, they all leave work at 4:30 p.m.,
arrive home at exactly 5:00 p.m., and go to bed at 9:00 p.m. Three fundraisers, Alpha,
Beta, and Charlie, have targeted Milltown’s population. To get a donation, they must
call Milltown’s residents after they get home from work but before they go to bed.
Because the charities raising the funds are identical, the first to call a willing donor will
get the donation. Calls made by the fundraisers will tend to be:
A. evenly distributed throughout the evening.
B. clustered near 5:00 p.m.
C. clustered near 6:00 p.m.
D. clustered near 7:00 p.m.
