Calculation of the Number of Students who Went on the Excursion and to the Cinema

To calculate the number of students who went on the excursion and to the cinema, we can use the information provided.

According to the given information: - The total number of students in the class is 30. - 23 students went on the excursion. - 21 students went to the cinema. - 5 students did not go on either the excursion or to the cinema.

To find the number of students who went on both the excursion and to the cinema, we can subtract the number of students who did not go anywhere from the total number of students.

Let's calculate it step by step:

1. Find the number of students who did not go anywhere: - 5 students did not go on either the excursion or to the cinema.

2. Subtract the number of students who did not go anywhere from the total number of students: - Total number of students: 30 - Number of students who did not go anywhere: 5 - Number of students who went on either the excursion or to the cinema: 30 - 5 = 25

Therefore, 25 students went on either the excursion or to the cinema.

Unfortunately, the exact number of students who went on both the excursion and to the cinema cannot be determined based on the given information.
