Since we have the symbol â‹‚, we are looking for the intersection of the given sets.
J&={4,5,6,7}
L&={x|xis an even whole number
& lessthan 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 the numerical form.
J&={4,5,6,7}
L&={0,2,4,6,8,10}
The intersection of two sets is the set that contains elements that are common in both sets. An element is in the intersection of J and L if it belongs to J and to L at the same time.
J&={ 4,5, 6,7}
L&={0,2, 4, 6,8,10}
J â‹‚ L&={ 4, 6}
