" 21.Let "A={x,y,z}" and "B={p,q}," then draw the tree "

Let A=(x,y,z) and B=(p,q), then draw the tree diagram of A xxB and BxxA .

SECTION MULTIPLE CORRECT CHOICE TYPE Example 41 Let a, b, c , p, q be five different non-zero real numbers and x, y, z be three numbers satisfying the system of equations a a-p aq then (a) x + y + z = a + b + c-p-q abc (b) x = pq 0 in (c) y = (a-p)(h-p)(c-p) p(p-q) (a-q)(b-q)(c-q) aq-p) (d) z = b.

The sides of triangle are denoted by x , y nd z . Area of the triangle and semiperimeter of the triangle are denoted by P and q respectively .If P= sqrtq (q-x)(q-y)(q-z) and x+y-z=y+z-x=z+x-y=4 Find P (in square units)

Let X = {a,b,c,p,q,r,x,y,z}, A= {b,q,y}, B={a,p,r,x,y} then (A nn B)'

Let X = {a,b,c,p,q,r,x,y,z}, A= {b,q,y}, B={a,p,r,x,y} then (A nn B)'
