Let A and B be subset of$\displaystyle R$ and consider the list

$\displaystyle L : x_A,x_B,x_a_(_i_n_t_e_r_s_e_t_c_t_i_o_n_)_b,$

of vectors in $\displaystyle F(R)$

(a) Show that if the condition A(∩)B is not = ∅ and A is not a subset of B and B is not a subset of A

Show that it is independent.

Pls help.
