Correct Answer - D Statement I if P(Hi∩E)=0 for some I, then P( Hi E )=P( E Hi )=0 If P(Hi∩E)≠O,∀ i=1,2,...,n,then P( Hi E )= P(Hi∩E) P(Hi) × P(Hi) P(E) = P( E Hi )×P(Hi) P(E) >P( E Hi )⋅P(Hi) [∴O<P(E)<1] Hence, Statement I may not always be true. Statement II Clearly, H1∪H2∪...∪Hn=S [same space ] ⇒ P(H1)+P(H2)+...+P(Hn)=1 Hence, Statement II is true.
