A student wants to count the number of shows that meet both of the following criteria.
Is a talk show
Is on Saturday or Sunday
For a given row in the spreadsheet, suppose genre contains the genre as a string and day contains the day as a string. Which of the following expressions will evaluate to true if the show should be counted and evaluates to false otherwise?
A. (genre = “talk”) AND ((day = “Saturday”) AND (day = “Sunday”))
B. (genre = “talk”) AND ((day = “Saturday”) OR (day = “Sunday”))
C. (genre = “talk”) OR ((day = “Saturday”) AND (day = “Sunday”))
D. (genre = “talk”) OR ((day = “Saturday”) OR (day = “Sunday”))
The correct answer is B: (genre = “talk”) AND ((day = “Saturday”) OR (day = “Sunday”)).
Explanation:
This expression checks two conditions:
1. The genre must be “talk”.
2. The day must be either “Saturday” or “Sunday”.
Using AND ensures that both conditions must be true for the show to be counted, while using OR allows for satisfying either of the weekend days. Options A, C, and D do not meet the criteria correctly for counting the shows as specified. If you have any more questions or need further assistance, feel free to ask!
