Question

 If n ( M ∩ N ) =2 , n (M) =5 , n (N) =6 then find the value of n ( M ∪ N )


​

Answer 1

Step-by-step explanation:

n ( M U N ) = n( M ) + n( N ) - n ( M ∩ N )

n ( M U N ) = n( M ) + n( N ) - n ( M ∩ N ) = 5 + 6 - 2

= 9

Answer 2

Answer:

If n ( M ∩ N ) =2 , n (M) =5 , n (N) =6 then find the value of n ( M ∪ N )
