Answer:
Step-by-step explanation:
A ∪ B -----> we have to write all the elements from A & B set without duplicating.
B∩C ------> We have to write only the elements that are found in both B set and C set
A) A ∪ B = {1,3,5, 6, 7, 9, 10,12}
b) A ∪ C = {1, 3, 5, 6, 7, 9, 10,2,4,8,12}
c) B ∩ C = {10,12}
Answer:
a. A U B = { 1,3,5,6,7,9,10,12 }
b. A U C = { 1,2,3,4,5,6,7,8,9,10,12}
c. B n C = { 10.12 }
Step-by-step explanation:
a. A U B — you put all the numbers in set A and B together without repeating anything.
A U B = { 1,3,5,6,7,9,10,12}
b. A U C — you put all the numbers in set A and C without repeating anything.
A U C = { 1,2,3,4,5,6,7,8,9,10,12}
c. B n C — you find a common number in sets B and C.
B n C = { 10,12}
The numbers 10 and 12 are the only common thing in sets B
and C.
