... children, age at death is recorded. However, these models fail to capture the non-zero probability of zero occurrence of an event. Since infant survival time involves both discrete (survival time = 0) and continuous part (survival time >0), a model which combines both circumstances namely the Tweedi ...

... .5, and therefore p = .5 and then the first equation implies that n=4. If X is binomial with n=4, p=.5, we need Prob{X ≥ 1} = 1 −Prob{X=0} = 1 .5 4 .9375. Answer is D. 3) If X=Profit, then E[X] = (50000)(.6) + 0(.4) = 30,000. Thus, Var(X)=(50000−30000)2(.6)+(0−30000)2(.4) = 600,000,000 so the st ...
