Since we have the symbol ⋃, we are looking for the union of the given sets.
J&={4,5,6,7}
L&={x|xis an even whole number
& less than 12}
We can rewrite the set L as a list of numbers. Out of all whole numbers smaller than 12, we will choose only those that are even.
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
Now, we have both sets written in numerical form.
J&={4,5,6,7}
L&={0,2,4,6,8,10}
The union of two sets is the set that contains allelements found in either set. Therefore, the union of J and L holds all elements that are in either J or L. Note that a union only contains unique values, so we will cross out the duplicates, if any.
J&={ 4,5, 6,7}
L&={0,2,4,6,8,10}
J ⋃ L&={0, 2, 4, 5, 6, 7, 8, 10}
