One indicator of the level of hardship was the increase in the number of people bringing items to a Paris pawnbroker; the number of people bringing items to the pawnbroker had increased to 658 per day (Bloomberg Business week, March 5–March 11, 2012).

b. On any given day, what is the probability that between 600 and 700 people bring items to the pawnshop?

c. How many people bring items to the pawnshop on the busiest 3% of days?
