ASSASSINATION can be arranged in 13!/(3!*4!*2!*2!) ways.


 


No two As coming together.


 


x  S  x  S  x  S  x  S  x  I  x  N  x  T  x  I  x  O  x  N x


 


A can be put in place of any x. (3 As can be put in 11 places in 11C3 ways).


 


No of favourable conditions = 10!/(4!*2!*2!) * 11C3


 


Probability = [10!/(4!*2!*2!) * 11C3]/[13!/(3!*4!*2!*2!)]

If p , q, n , l > 0 and the ratio of the roots of equation : lX^2 + nx + n = 0 be p:q then proove that p/q^1/2 + q /p^1/2 – n/l^1/2 = 0
 
 
Hello student, the ratio is p : q so let roots bept and qt. so pt + qt = - n/l => p + q = - n/(lt) and pqt^2 = n/l => pq = n/(lt^2) now (p/q)^1/2 + (q/p)1/^2 = (p + q)/(pq)^(1/2) =...

A diagonal of rhombus ABCD is a member of both the family lines (x+y-1)+k1(2x+3y-2)=0 and (x-y+2)+k2(2x-3y+5) where k1,k2 are Real Numb and one of the vertex of the rhombus is (3,2). If the...
 
 
One diagonal is a member of both the family of lines (x+y-1)+k1(2x+3y-2)=0 and (x-y+2)+k2(2x-3y+5) Hence it must pass through the point of intersection of x+y-1= 0 and 2x+3y-2 = 0 . Also it...
