For two non - zero complex numbers A and B, if `A+(1)/(B)=barA and (1)/(A)+B=barB`, then

If a and b are two distinct non-zero real numbers such that a -b =a/b=1/b-1/a, then : (a) a>0 (b) a 0

If two events A and B are such that P (barA) = 3/10 and P(A nn barB) = 1/2 , then P(A nn B) is

If a and b are two distinct non-zero real numbers such that a -b =a/b=1/b-1/a, then :

If bara and barb two non collinear vectors then the points l_(1)bara+m_(1)barb, l_(2)bara+m_(2)barb, l_(3)bara+m_(3)barb are collinear if

If bara, barb are two non-zero vectors and c is nonzero scalar, and bara. barr = c, bara xx barr = barb then barr =

If bara and barb are non-zero vectors such that abs(bara+barb)^(2) = absbara^(2) +absbarb^(2) , then find the angle between bara and barb

If A and B are two independent events such that P( barA nnB)=2//15 and P(Ann barB )=1//6 , then P(B) is

If A and B are two independent events such that P( barA nnB)=2//15 and P(Ann barB )=1//6 , then P(B) is
