Question 1051883
.
I need help, I can't seem to understand this problem


Suppose Set A contains 84 elements and the total number elements in either Set A or Set B is 133. 
If the Sets A and B have 1 elements in common, how many elements are contained in set B?
~~~~~~~~~~~~~~~~~~~~~~~~~~


1.  The very first phrase in your formulation doesn't make sense, so I omitted it.


2.  Regarding the remaining part, the answer is:


          The number of elements in the set B is   133 - 84 + 1.
