How to Find Probability from a Z-Score (With Examples)

Web1 In short, just subtract the values in this table above from 1. So for a z-score of -2, with a p-value of 0.5, that gives (1- 0.9798) = 0.0202 You will get a negative z-score when x is less than μ in the following equation: z = x − μ σ As z-scores move from negative to positive they are moving from left to right on the bell curve. WebNumber of ways it can happen: 4 (there are 4 blues) Total number of outcomes: 5 (there are 5 marbles in total) So the probability = 4 5 = 0.8 Probability Line We can show probability … grammarly keyboard download for windows
