If ={ x: x in W, x le 10 } and B = { x: ...

`If ={ x: x in W, x le 10 } and B = { x: x in N x le 10 } " then find " n( A cup B)`
The following steps are involved in solving the above problem.Arrange them in sequential order
(A) `rArr n(A cup B)=11`
( B) `A cup B=`{0,1,2,3,4,5,6,7,8,9, 10 } cup {1,2,3,4,5,6,7,8,9,10}
Form the given data A={1,2,34,5,6,7,8,9,10} and B={1,2,3,4,5,6,7,8,9,10}
`therefore A cup B ={0,1,2,3,4,5,6,7,8,9,10}`
