WebProbability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can only predict the chance of an event to occur. In … WebJan 5, 2024 · Given two events, A and B, to “find the probability of A or B” means to find the probability that either event A or event B occurs. We typically write this probability in one of two ways: P(A or B) – Written form; P(A∪B) – Notation form; The way we calculate this probability depends on whether or not events A and B are mutually ...
WebAnswer. For this problem, we know p = 0.43 and n = 50. First, we should check our conditions for the sampling distribution of the sample proportion. n p = 50 ( 0.43) = 21.5 and n ( 1 − p) = 50 ( 1 − 0.43) = 28.5 - both are greater than 5. Since the conditions are satisfied, p ^ will have a sampling distribution that is approximately normal ...
