B) Relative frequency theory.
C) Subjectivist theory.
D) Conditional theory.
E) Relativist theory.

Question

Quizplus · Accepted Answer

The most appropriate theory for computing the probability of rocket engine failure would be the relative frequency theory. This theory calculates the probability of an event based on the number of times it has occurred in the past. In this case, past data on similar rocket engines could be used to estimate the probability of premature failure. The classical theory would not be appropriate as it assumes all outcomes are equally likely, which is not the case for rocket engine failure. The subjectivist theory would be based on personal beliefs and opinions, which is not reliable for this type of calculation. The conditional theory is used when the outcome depends on a specific condition, which does not apply in this case. The relativist theory is not a commonly used theory in probability calculations.
