n(AxB) = 25
Step-by-step explanation:
AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.
Given
A = {a,b,c,d,e}
B = {1,2,3,4,5}
The number of elements for Cartesian product of two sets is determined by:
![n(AxB) = n(A) * n(B)](https://tex.z-dn.net/?f=n%28AxB%29%20%3D%20n%28A%29%20%2A%20n%28B%29)
Here
![n(A) = 5\\n(B) = 5](https://tex.z-dn.net/?f=n%28A%29%20%3D%205%5C%5Cn%28B%29%20%3D%205)
So,
![n(AxB) = 5*5 = 25](https://tex.z-dn.net/?f=n%28AxB%29%20%3D%205%2A5%20%3D%2025)
Hence,
n(AxB) = 25
