If A cancelsub B " and " B cancelsub C ....

If `A cancelsub B " and " B cancelsub C` .Is this statement true ? A is not subset of C

Text Solution

Verified by Experts

Let A= ={ 1,2 } B={ 0,6, 8 } and C= { 0,1,2,6,9}
Here , `A cancelsub B " and " B cancelsub C` " but " A sub C.`
So the given statement is false .
