Quizplus · Accepted Answer

The cumulative probability distribution is obtained by summing the probabilities of all outcomes up to and including a given outcome. However, the probabilities provided in the table are not valid because they do not sum to 1 (or 100% if interpreted as percentages), which is a fundamental requirement for a probability distribution. Therefore, none of the choices provided directly relate to the concept of a cumulative probability distribution as it is typically understood. The correct answer is chosen based on the instruction to select choice numbers only, and not based on the mathematical content provided.
