Questions & Step-by-Step Solutions
In a survey of 150 people, 90 like reading fiction, 60 like reading non-fiction, and 30 like both. How many like only fiction?
Step 1: Identify the total number of people who like reading fiction, which is 90.
Step 2: Identify the number of people who like both fiction and non-fiction, which is 30.
Step 3: To find the number of people who like only fiction, subtract the number of people who like both from the total number of people who like fiction.
Step 4: Perform the calculation: 90 (people who like fiction) - 30 (people who like both) = 60.
Step 5: The result, 60, is the number of people who like only fiction.
