i. S∩T∩W = S ii. S∪T∪W = W ii. T∩W = S If S⊂ ⊂ T⊂ ⊂ W. Which of the above statements are true?

Answer Details

From the given statements, we know that: i. S∩T∩W = S: This means that the elements that are common to S, T, and W are only those in S. ii. S∪T∪W = W: This means that the union of S, T, and W includes all the elements in W. iii. T∩W = S: This means that the elements that are common to T and W are only those in S. Using these statements, we can conclude that: - Statement i is true because it tells us that the only elements that are common to S, T, and W are those in S. This means that S is a subset of both T and W, which is consistent with statement iii. However, statement ii doesn't provide any additional information about the relationship between S, T, and W. - Statement ii is false because it tells us that the union of S, T, and W includes all the elements in W. This means that W is a subset of S∪T, which is inconsistent with statement iii. We know that S is a subset of both T and W, but this doesn't necessarily mean that S is a subset of S∪T. - Statement iii is true because it tells us that the elements that are common to T and W are only those in S. This means that S is a subset of both T and W, which is consistent with statement i. Therefore, the correct answer is: i and iii are true.
