Given that a customer does not make a purchase, there is still a
prominent prompt to be added to the website's mailing list for
future promotions. Previous experience has shown that roughly
21% of these customers will choose to be added. What is the
probability that the next customer will not make a purchase and
be added to the mailing list? (Hint: what law from chapter 3 may
help with this?)

- Here’s a look at a map of the east side of Dubuque, Iowa. It shows a driving path from a casino on the river to a golf course on the other side. According to the maps app on my phone, the driving distance is 3.0 miles. We’re most interested in the graphic at the bottom left, which indicates that 1 inch on the map (measure if you don’t believe me) corresponds to 2,000 feet in real life.
