How to Calculate Normal Probability
Normal probability calculates the number of occurrences for an event based on a certain number of possible outcomes. The calculation is generally expressed as a percentage or a number from zero to one. Single event probability is the most common... More »

Sep 18, 2017 ... The Normal Probability Distribution is very common in the field of statistics. Whenever you measure things like people's height, weight, salary, opinions or votes, the graph of the results is very often a normal curve. The Normal Distribution. A random variable X whose distribution has the shape of a normal ...

Because I don't know what style of normal tables you have, I can't tell you exactly how to use yours. Under the standard normal curve below, there are four areas bounded by vertical broken lines. From left to right their areas are 0.345, 0.155, 0.155, and 0.345, respectively. You will have to look in the body of ...

normal distribution 95%. You can see on the bell curve that 1.85m is 3 standard deviations from the mean of 1.4, so: Your friend's height has a "z-score" of 3.0. It is also possible to calculate how many standard deviations 1.85 is from the mean . How far is 1.85 from the mean? It is 1.85 - 1.4 = 0.45m from the mean. How many ...
