   Hi
   the first part of the question request to prove the following:
   my(t) = pmx1 (t) + (1-p)mx2 (t)
   I don't understand the explanation of the exam report.
   can someone give me further details?

   They've quoted the definition of the MGF of Y and then just used the standard application of E(g(X)) from CT3:
   
   \(E[g(X)] = \sum g(x)P(X=x)\)
