Which of the following sequence of set operations counts the number of elements that are in exactly one of A, B or C?"
Options:
∣A∩B∣+∣B∩C∣+∣C∩A∣−3(∣A∩B∩C∣)
∣A∣+∣B∣+∣C∣−2(∣A∩B∣+∣B∩C∣+∣C∩A∣)+3∣A∩B∩C∣
∣A∩B∣+∣B∩C∣+∣C∩A∣−2∣A∩B∩C∣
∣A∣+∣B∣+∣C∣−∣A∩B∣−∣B∩C∣−∣C∩A∣+∣A∩B∩C∣
∣(A∩B∩C)∪(A∩BC∩CC)∪(AC∩B∩CC)∪(AC∩BC∩C)∣
|A∪B∪C |
