Survey Results on Favorite Cartoons among 6th Graders

In a survey conducted among sixth-grade students to determine their favorite cartoons, the top three most popular cartoons were "Snow White and the Seven Dwarfs," "SpongeBob SquarePants," and "The Wolf and the Calf." The class consists of a total of 38 students. Among them, 21 students chose "Snow White and the Seven Dwarfs," with three of them also naming "The Wolf and the Calf," six naming "SpongeBob SquarePants," and one student listing all three cartoons. "The Wolf and the Calf" was chosen by 13 students, with five of them selecting two cartoons simultaneously.

Calculation of Students Choosing "SpongeBob SquarePants"

To calculate the number of students who chose "SpongeBob SquarePants," we can use the information provided in the survey results.

Out of the 38 students, 21 chose "Snow White and the Seven Dwarfs," 13 chose "The Wolf and the Calf," and 1 chose all three cartoons. This leaves us with 38 - 21 - 13 - 1 = 3 students who did not choose "Snow White and the Seven Dwarfs," "The Wolf and the Calf," or all three cartoons. Therefore, the number of students who chose "SpongeBob SquarePants" is 6 + 3 = 9.

Answer

The number of students who chose the cartoon "SpongeBob SquarePants" is 9.
