Need full explanation ​

Answer 1

      

      n(S) = 21 n(T) = 32

      n(S) = 21 n(T) = 32S ∩ T =11

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,    

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,    S ∪ T = n(S) + n(T) - S ∩ T Substituting the values ,we get

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,    S ∪ T = n(S) + n(T) - S ∩ T Substituting the values ,we get      

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,    S ∪ T = n(S) + n(T) - S ∩ T Substituting the values ,we get      S ∪ T = n(S) + n(T) - S ∩ T                 =21 + 32 - 11 = 53 - 11 = 42

      n(S) = 21 n(T) = 32S ∩ T =11S ∪ T = ?we know that ,    S ∪ T = n(S) + n(T) - S ∩ T Substituting the values ,we get      S ∪ T = n(S) + n(T) - S ∩ T                 =21 + 32 - 11 = 53 - 11 = 42Hope this helps You!!!
