What is Probability?
In Mathematics, Probability theory is the study of chances. In real life, we predict chances depending on the situation. But Probability theory is bringing a mathematical foundation for the concept of Probability. For example, if a box contain 10 balls which include 7 black balls and 3 red balls and randomly chosen one ball. Then the Probability of getting red ball is 3/10 and Probability of getting black ball is 7/10. When coming to statistics, Probability is like the back bone of statistics. It has a wide application in decision making, data science, business trend studies, etc.
How to Calculate Normal Probability Distribution?
Normal Probability Distribution calculator uses Normal Probability Distribution Function = 1/(Standard Deviation of Normal Distribution*sqrt(2*pi))*e^((-1/2)*((Number of Successes-Mean of Normal Distribution)/Standard Deviation of Normal Distribution)^2) to calculate the Normal Probability Distribution Function, The Normal Probability Distribution formula is defined as the likelihood of a continuous random variable falling within a specific range (usually defined by a mean and standard deviation). It is characterized by a symmetrical and bell-shaped curve and models the probability of observing a value within a range, assuming a normal or approximately normal distribution of the data. Normal Probability Distribution Function is denoted by PNormal symbol.
How to calculate Normal Probability Distribution using this online calculator? To use this online calculator for Normal Probability Distribution, enter Standard Deviation of Normal Distribution (σNormal), Number of Successes (x) & Mean of Normal Distribution (μNormal) and hit the calculate button. Here is how the Normal Probability Distribution calculation can be explained with given input values -> 0.150569 = 1/(2*sqrt(2*pi))*e^((-1/2)*((7-5.5)/2)^2).
