If A={a , b ,\ c , d},\ B={p , q , r , s} than Is the following relation from A\ to\ B ? Give reasons for your answer.: R_3={(a , p),\ (a , q),\ (d , p),\ (c , r),\ (b , r)}

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

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

If A , B and C are three exhaustive and mutually exclusive events such that P(B) = 3/2P(A) and P( C) = 1/2P(B) , then P(AcupC) is
