Question

Quizplus · Accepted Answer

The principle of indifference states that if there is no reason to believe one outcome is more likely than the others, then all possible outcomes are equally probable. Therefore, choice A is the correct answer. Choice B is not related to the principle of indifference. Choice C implies that some outcomes are more probable and contradicts the principle of indifference. Choice D is not related to the principle of indifference in this context. Choice E is not necessarily true since different theories may lead to different probability calculations.
