a={1,3,4}, b={x| x is an even whole number less than 9}, c={2,5,7,10}, and d = {x| x is an odd whole number less than 10}
b U c
b: make a list of all the even whole numbers less than 9
c: you have that list given to you
what numbers do you see that belong to b OR to c
To find the union of sets b and c, you need to combine all the elements from both sets while removing any duplicates. Here's how you do it:
1. Write down the elements of set b: {x| x is an even whole number less than 9}. Since the whole numbers less than 9 that are even are 2, 4, 6, and 8, we have: b = {2, 4, 6, 8}.
2. Write down the elements of set c: {2, 5, 7, 10}.
3. Combine the elements of sets b and c, while removing any duplicates. The union of sets b and c, denoted b U c, is given by: {2, 4, 6, 8, 5, 7, 10}.
Therefore, the union of sets b and c is {2, 4, 6, 8, 5, 7, 10}.
