A college survey was taken to determine where students study. Of 108 students surveyed, 70 studied in the cafeteria, 54 studied in the student lounge, 24 studied in both the cafeteria and the student lounge.

Of those interviewed how many did not study in either the cafeteria or the student lounge?

The set D U E represents the union of sets D and E. To find the elements in this set, we combine all the elements from both sets, removing any duplicates.

D U E = {16, 19, 21, 18, 20}

Therefore, the elements in the set D U E are: 16, 19, 21, 18, 20.

To find the union of sets D and E, we need to combine all the elements from both sets, removing any duplicates.

Given:
D = {4,7,9}
E = {4,6,7,8}

To find D U E, we combine the elements from both sets:

D U E = {4, 7, 9, 6, 8}

So, the elements in the set D U E are: {4, 7, 9, 6, 8}.

To find the intersection of sets A and C, we need to identify the elements that are common between the two sets.

Given:
A = {1, 3, 5}
C = {6, 8, 10, 12}

To find A ∩ C, we determine the elements that are present in both sets A and C:

A ∩ C = {}

Since there are no common elements between sets A and C, the intersection A ∩ C is an empty set.

To find the intersection of sets B and C, we need to identify the elements that are common between the two sets.

Given:
B = {x | x is an even whole number less than 9}
C = {1, 4, 6, 7}

To find B ∩ C, we determine the elements that are present in both sets B and C:

B ∩ C = {4, 6}

Therefore, the intersection B ∩ C contains the elements {4, 6}.

To find the intersection of sets B and D, we need to identify the elements that are common between the two sets.

Given:
B = {x | x is an even whole number less than 11}
D = {x | x is an odd whole number less than 12}

To find B ∩ D, we determine the elements that are present in both sets B and D:

B = {2, 4, 6, 8, 10}
D = {1, 3, 5, 7, 9, 11}

B ∩ D = { }

Since there are no common elements between sets B and D, the intersection B ∩ D is an empty set.

To find the number of students who did not study in either the cafeteria or the student lounge, we can subtract the number of students who studied in either the cafeteria or the student lounge from the total number of students surveyed.

Given:
Total number of students surveyed = 108
Number of students who studied in the cafeteria = 70
Number of students who studied in the student lounge = 54
Number of students who studied in both the cafeteria and the student lounge = 24

To find the number of students who did not study in either the cafeteria or the student lounge, we subtract the number of students who studied in either the cafeteria or the student lounge from the total number of students surveyed:

Number of students who did not study in either the cafeteria or the student lounge = Total number of students surveyed - Number of students who studied in either the cafeteria or the student lounge

Number of students who did not study in either the cafeteria or the student lounge = 108 - (70 + 54 - 24)

Number of students who did not study in either the cafeteria or the student lounge = 108 - 100

Number of students who did not study in either the cafeteria or the student lounge = 8

Therefore, 8 students did not study in either the cafeteria or the student lounge.

To find the intersection of two sets, we need to identify the elements that are common to both sets.

Given:
Set A = {1, 3, 6, 8}
Set B = {2, 5, 7}

To find A n B (the intersection of A and B), we determine the elements that are present in both sets A and B:

A n B = {}

Since there are no common elements between sets A and B, the intersection A n B is an empty set.

To find the number of students who like only tennis and football, we need to subtract the students who like tennis, football, and baseball (4) from the students who like tennis and football (14).

Given:
Number of students who like tennis = 20
Number of students who like football = 26
Number of students who like tennis and football = 14
Number of students who like tennis and baseball = 19
Number of students who like football and baseball = 8
Number of students who like all three sports = 4
Number of students who like none of the sports = ?

Number of students who like only tennis and football = Number of students who like tennis and football - Number of students who like all three sports
= 14 - 4
= 10

Therefore, 10 students like only tennis and football.

I apologize for the mistake. Let me correct it.

To find the number of students who like only tennis and football, we need to subtract the students who like tennis, football, and baseball (4) as well as the students who like tennis and baseball (19), from the students who like tennis and football (14).

Given:
Number of students who like tennis = 20
Number of students who like football = 26
Number of students who like tennis and football = 14
Number of students who like tennis and baseball = 19
Number of students who like football and baseball = 8
Number of students who like all three sports = 4
Number of students who like none of the sports = ?

Number of students who like only tennis and football = Number of students who like tennis and football - Number of students who like all three sports - Number of students who like tennis and baseball
= 14 - 4 - 19
= -9

Since the resulting number is negative, it suggests that there was an error in the given data. The number of students who like only tennis and football cannot be negative. Please double-check the information provided and make sure all the counts are accurate.
