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?)
