Question

[ A,B,C are the sets of letters needed to spell the words STUDENT,PROGKESS and CONGRUENT respectively.Then n(A uu(B nn C)) is equal to ]

Answer 1

Answer:

Set A contain {C,o,l,e,g} 5 letters

Set B contian {m,a,r,i,g,e} 6 letters

Set C contain {l,u,a,g,e} 5 letters

now (BUC)={m,a,r,i,g,e,l,u}

and [A-(BUC)]={c,o}

(subtract the letter containing in a (BUC) from SET A)

NOW second part

A-B={c,o,l}

A-c={c,o}

now intersection of these two are

[(A-B)n (A-C)]={c,o}

so therefore

we get

[A-(BUC)]=[(A-B)n(A-c)].
