Mathematics 2009 JAMB Past Questions - Question 11: I. S nTnW=S II.S U T U W=W III.T n W=S if S (T (W ,which of the above statements are true ?

Correct Answer

A

Explanation

SnTnW →W is the universal setTnW =S → True 1and3 Let's analyze each statement:I. S nTnW = SThis statement is not clear as it is missing some information. The symbol "n" is not a commonly used set operation, so it's difficult to determine the meaning of this statement without further clarification.II. S U T U W = WThis statement is true if S is a subset of W. In set notation, the union of sets S, T, and W (S U T U W) will be equal to set W if all the elements of set S are already included in set W.III. T n W = S if S (T (WThis statement is not clear as it is missing some information. The symbol "n" is not a commonly used set operation, so it's difficult to determine the meaning of this statement without further clarification.In summary, only statement II is true if S is a subset of W.
