It is given that `A=B^2`. If `A=100+-0.20`, then B is equal to

If A and B are two matrices such that A B=A and B A=B , then B^2 is equal to (a) B (b) A (c) 1 (d) 0

If A = [(1,0),(1/2,1)] , then A^100 is equal to

For any 2xx2 matrix, if A\ (a d j\ A)=[[10 ,0 ],[0 ,10]] , then |A| is equal to (a) 20 (b) 100 (c) 10 (d) 0

In a DeltaABC , if a 100, c = 100 sqrt(2) and A=30^(@) , then B equals to

If a binary operation * is defined by a * b=a^2+b^2+a b+1 ,then (2 * 3) * 2 is equal to (a) 20 (b) 40 (c) 400 (d) 445

If A and B are two events such that P(A) = 0.6 , P(B) = 0.2 and P(A/B) = 0.5 , then P(A'/B') is equal to

If A=[{:(1,0,0),(0,1,0),(a,b,-1):}] then A^(2) is equal to

If A=[{:(1,0,0),(0,1,0),(a,b,-1):}] then A^(2) is equal to

If A and B are two events such that P(A) =0.6 , P(B) = 0.2 and P(A//B) = 0.5 , then P(A,B)is equal to

If A and B are two events such that P(A) =0.2 , P(B) = 0.4 and P( A cup B) = 0.6 then P(A/B) is equal to
