Let U 27 28 29 30 31 32 33 34 35 36 A 30 31 32 33 B 27 29 31

Let
U ={27, 28, 29, 30, 31, 32, 33, 34, 35, 36}

A ={30, 31, 32, 33}

B ={27, 29, 31, 33, 35}

C ={28, 30, 31, 35, 36}

Find the set.
(A B)\' C =

Solution

A B={30, 31, 32, 33}{27, 29, 31, 33, 35}

={27, 29,30, 31,32, 33, 35}

(A B)\' =U-(A B)={27, 28, 29, 30, 31, 32, 33, 34, 35, 36}-{27, 29,30, 31,32, 33, 35}

               ={ 28, 34, 36}

(A B)\' C ={ 28, 34, 36}{28, 30, 31, 35, 36}

                     ={28, 36}
