Question

P= {1,3,5,7,9} ; Q={2,4,6,8,} then find (PnQ)u(PnQ) and p-(PuQ) and (PuQ)-p

Answer 1

P ={4,5,6,7,8} as x is greater than equal to 4 but less than or equal to 8

And Q={1,2,3,4,5} as x is a natural number less than 6

Union of two sets has all the elements of both the sets

So, P∪Q={1,2,3,4,5,6,7,8}

And Intersection of two sets has the elements common in both the sets

So, P∩Q={4,5}.
