Let `A={p,q,r,s} and B ={q,r,p,s }`, Are A and B equal ?

Let A = {p, q, r,s}, B = {p, q, r} and C = {q, s}. Find all sets X such that : X sub A and X cancel (sub) B .

Let A = {p, q, r,s}, B = {p, q, r} and C = {q, s}. Find all sets X such that : X sub B and X sub C

Let A = {p,q,r,s},B={p,q,r} and C= {q,S} . Find all sets X such that : (i) XsubBandXsubC (ii) XsubAandX!inB .

If A = {p,q,r, s} and B = {1, 2, 3} , find which of the following is not a function from A to B? A. R_1={(p,1),(q,2),(r,1),(s,2)} B. R_2={(p,1),(q,1),(r,1),(s,1)} C. R_3={(p,1),(q,2),(p,2),(s,3)} D. R_4={(p,2),(q,3),(r,2),(s,2)} ANSWER: C

List the sets A,B and C , given that, A cupB={p,q,r,s}, A cupC ={q,r,s,t}, A cap B={q,r}, A cap C={q,s}.

Let A={p , q , r , s}\ a n d\ B={1,2,3}dot Which of the following relations from A to B is not function? (i) R_(1) = {(p, 1), (q, 2), (r, 1), (s, 2)} (ii) R_(2) = {(p, 1), (q, 2), (r, 1), (s, 1)} (iii) R_(3) = {(p, 1), (q, 2), (r, 2), (r, 2)} (iv) R_(4) = {(p, 2), (q, 3), (r, 2), (s, 2)}

If A={p,q,r,s}, B={r,s,t,u} and C={p,q,r}, then (A-B)-C is .........

Let A=[(1, 2),(3, 4)] and B=[(p,q),(r,s)] are two matrices such that AB = BA and r ne 0 , then the value of (3p-3s)/(5q-4r) is equal to

Let A=[(1, 2),(3, 4)] and B=[(p,q),(r,s)] are two matrices such that AB = BA and r ne 0 , then the value of (3p-3s)/(5q-4r) is equal to

Are the following pair of sets equal? Give reasons A= {p, q, r, s} B= {q, p, s, r} .
