From a portion of a probability distribution, you read that P(demand = 0) is 0.05 and P(demand = 1) is 0.10. The cumulative probability for demand 1 would be A) 0.05 B) 0.075 C) 0.10 D) 0.15 E) cannot be determined

Question

Quizplus · Accepted Answer

The cumulative probability for demand 1 is the sum of the probabilities for all demand levels up to and including 1. Thus, it is P(demand = 0) + P(demand = 1) = 0.05 + 0.10 = 0.15.
