Answer:
20
Step-by-step explanation:
Let A, B, C and D sets.
Let |A| the number of elements of A.
Remember, the quantity of elements that have the set is
1. Since each set has 100 elements,
2. each pair of the sets shares 50 elements
3. each three of the sets share 25 elements,
4. the four sets share 5 elements
Then
So, there are 20 elements in the union of the sets A, B, C and D
