Let A = {x , y , z} " and " B = {1, 2}. ...

Let `A = {x , y , z} " and " B = {1, 2}`. Find the number of relations from `A` to `B`.

Text Solution

Verified by Experts

Given `A = {x , y , z} " and " B = {1, 2}`
`therefore AxxB`=`{(x,1),(x,2),(y,1),(y,2),(z,1),(z,2)}`
since n(`AxxB`)=`6`
The number of subsets of `AxxB` is `2^6`
