WebThe normal distribution is described by two parameters: the mean, μ, and the standard deviation, σ. We write X - N (μ, σ 2 ). The following diagram shows the formula for Normal Distribution. Scroll down the page for more … Web10 de abr. de 2024 · We are required to find the probability that y lies between 50 and 70 or P ( 50 < y < 70) We find the probability through the standard normal distribution formula given below: z = (X– Mean) / Standard deviation. If we consider x = 50 , then z = (50 – 50) / 15 = 0. If we consider x = 70 , then z = (70 – 50) / 15 = 1.33.
