A,B,C are the sets of letters needed to spell the words `STUDENT`, `PROGRESS` and `CONGRUENT` respectively. Then `n(A uu(B nn C))=`

Find the region (A nn B')'uu(B nn C)

A,B,C are the sets of the letters in the words 'college' marriage' and 'luggage' respectively, verify that [A-(B uu C)]=[(A-B)nn(A-C)]

Show that the set of letters needed to spell CATARACT and the set of letters needed spell TRACT are equal.

Show that the set of letters needed to spell CATARACT and the set of letters needed to spell TRACT are equal.

If A and B are two sets then A-(B uu C)=(A-B)nn(A-C)

If A and B are two sets then A-(B nn C)=(A-B)uu(A-C)

(A uu B) nn (A uu B ^ (c)) = A

If A and B are two sets then A nn(B-C)=(A nn B)-(A nn C)

If A and B are two sets, then A nn (A uu B) equals

If A and B are two sets, then A nn (A uu B) equals
