If P={a,b,c} and Q={r}, form the sets `P xx Q and Q xx P`.

If P = {4,3,2} and q={5} , form the sets P xx Q and Q xx P are these two products equal ?

If P={1,2}, form the set P xx P xx P

For any three sets P, Q and R, P-(QcapR) is

If A={p,q,r} and B={q,p,r}. Then check whether A=B or not.

If a ,b ,a n dc are in A.P. p ,q ,a n dr are in H.P., and a p ,b q ,a n dc r are in G.P., then p/r+r/p is equal to a/c-c/a b. a/c+c/a c. b/q+q/b d. b/q-q/b

If a, b and c are respectively the p^(th) , q^(th) and r^(th) terms of an A.P., then |(a" "p" "1),(b" "q" "1),(c" "r" "1)|=

If a,b,c are p^(pt),q^(th) and r^(th) terms of an A.P., find the value of |(a,b,c),(p,q,r),(1,1,1)| .

A fair dice is thrown three times. If p, q and r are the numbers obtained on the dice, then find the probability that i^(p) + i^(q) + i^(r) = 1 , where I = sqrt(-1) .
