The two photos present a problem related to set theory and survey analysis in which different coffee preferences are recorded. To summarize the key data and questions:

Data from the survey (from the first image):

• 221 like espresso.
• 127 like cappuccino and chocolate-flavored coffee.
• 182 like cappuccino.
• 136 like espresso and chocolate-flavored coffee.
• 209 like chocolate-flavored coffee.
• 78 like all three types of coffee.
• 116 like espresso and cappuccino.
• 82 like none of these types of coffee.

Questions (from the second image):

• a. How many of the customers in the survey like only chocolate-flavored coffee?
• b. How many like cappuccino and chocolate-flavored coffee but not espresso?
• c. How many like espresso and cappuccino but not chocolate-flavored coffee?
• d. How many like exactly one of the three types of coffee?

To solve these, we can use Venn diagrams or set theory equations. The key sets are:

• $E$ = Set of people who like espresso.
• $C$ = Set of people who like cappuccino.
• $Ch$ = Set of people who like chocolate-flavored coffee.

Would you like me to proceed with calculating the values based on this data?
