If `A=[[1,7],[2,5]] B=[[p,q],[a,b]]` and A=B. then the value of a is

If tan(A+B)=p&tan(A-B)=q , then the value of tan 2A is

If P(A) = 1/2, P(A cup B) = 3/5 and P (B) =q find the value of q is A and B are (i) Mutually exclusive (ii) independent events.

If A={1,2,3,4,5} and B={1,3,5,7,9} then find the value of (A-B)uu(B-A)

If a!=p,b!=q,c!=r and det[[p,b,ca,q,ca,b,r]]=0, then find the value of (p)/(p-a)+(q)/(q-b)+(r)/(r-c)

5.If the origin is the centroid of the trianglewhose vertices are A (2.p.-3), B(4,-2,5) andC(-5. 1.), then find the values of p q andr,

If(a+b)=5,then the value of (a-3)^(7)+(b-2)^(7) is:
