If the set A has p elements, B has q elements then the number of elements in A×B is
p+q
p+q+1
pq
p2
Explanation for the correct option
Given that,
set A has p elements ⇒nA=p
set B has q elements ⇒nB=q
We know that number of elements in set A×Bis nA×B=nA×nB
Here, nA×B=pq
Hence, the correct option is option (C) i.e. pq.
If the set A has p elements, B has q elements, then the number of elements in A×B is
If set A has p elements and set B has q elements, then the number of elements in set (A × B) is _____.
If set A has p element and set B has q elements, then the number of element in set (A × B) is _____.
