Use this probability calculatorr for determining probabilities of two events and probability of normal distribution. Each probability calculatorr shows all the probabilities possible.
Probability of Two Events
Probability of a Normal Distribution
Probability Of Two Events
Probability refers to the likelihood whether or not an event will occur. It can be any number falling between 0 and 1 where 1 signifies certainty while 0 signifies that an event won't occur. It also follows that if the probability of an event is higher, it will be more certain to occur. Generally, probability is defined as desired outcomes of an event divided by its total outcomes. It is also affected by the independence and mutual exclusiveness of the events that are being studied among several other things. This probability calculatorr can be used for determining probability of two events that one of them won't occur, event A and/or event B occur in case when they aren't mutually exclusive, both the events occur, and that either of the two events occur but both do not occur together.
What Is Normal Distribution?
The Gaussian Distribution or Normal Distribution refers to continuous probability distribution which follows function of:
where 
refers to the mean value while 
refers to variance. It should also be kept in mind that the standard deviation is usually denoted by 
. Furthermore, in special case in which = 1 and = 0, the distribution becomes standard normal distribution.
How This Probability Calculator Works?
The probability calculator page features two different calculators. One of them tells you the probability of two events while the other can be used for determining probability of normal distribution.
The first probability calculator requires you to enter probability of two events A and B. Remember it should be any number between 0 and 1. So, just enter the two probability values and the calculator will tell you different possible probabilities of two events as described above. You get probability values for cases when event A doesn't occur, when event B doesn't occur, when event A and/or event B occur, when both the events occur, and when either of the two events occurs but not both of them.
The second probability calculator that can be used for determining probability of normal distribution requires you to enter the Mean value, Standard Deviation, Left Bound value and the Right Bound value. While specifying left bound value, you can use '- inf' to mention negative infinite. Similarly, when you have to enter the right bound value, you can use 'inf' to mention positive infinite. Once all the values have been provided, hit the calculate button and the calculator will tell you the probability between the provided left bound and right bound values, the probability of left bound or less and the probability of right bound or less.
So, if you have to find out any of these probabilities for events or for the normal distribution, you can rely on the results from this probability calculator.
