WebbSolution: a) Standard probability definition. Let a random event meet following conditions: number of the events is finite. all events have the same chance to occur. no two events can occur in the same time. Probability of an event A equals , n = # of all possible events, m = number of cases favorable for the event A. Stands: 0 ≤ P (A) ≤ 1. Webb10 apr. 2024 · 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 P ( 50< x< 70) = P ( 0< z < 1.33) = [area to the left of z = 1.33] – [area to the left of z = 0] WebbFor example, for 1 red card, the probability is 6/20 on the first draw.
