The images you uploaded contain information about a coffee survey and related questions. To solve the problem accurately, let's break down the information from both images.

Information Extracted:

1. Survey Details (First Image):

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

2. Questions (Second Image):

   • a. How many of the customers 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?

Plan for solving:

We can solve this using set theory and Venn diagrams. There are three sets:

• E (espresso lovers)
• C (cappuccino lovers)
• Ch (chocolate-flavored coffee lovers)

By using the principle of inclusion-exclusion and the information provided, we can determine the number of people who fall into each subset.

Would you like me to proceed with solving this step-by-step, including drawing the Venn diagram to illustrate the breakdown?
