Answer 1

Answer:

Answer:

The value of the n (A U B) is 373 .

Step-by-step explanation:

Now by using the property .

n (A - B) = n (A U B) - n (B)

As given

n(A) = 115 , n(B) = 326 , n(A-B) = 47

Put in the above property.

47 = n (A U B) - 326

n (A U B) = 326 + 47

n (A U B) = 373

Therefore the value of the n (A U B) is 373 .
