Hi Ayushya.. :)
9) P(None of them occurs) = P(ȦḂĊ) = P(Ȧ)*P(Ḃ)*P(Ċ)
[As A,B,C are independent and its easy to show that Ȧ,Ḃ,Ċ will also be independent. ]
Therefore, P(None of them occurs) = (1-p1)(1-p2)(1-p3)
Note: Ȧ is complement of A, Ḃ is complement of B and Ċ is complement of C.
25) Use the definition of continuity.
