Probability Calculator Probability Calculator Probability is a part of mathematics is relate with the random phenomenon. Probability Calculator is an online tool to find probability of a given situation or problem. It makes calculation easy and fun. If numbers of possible outcomes and numbers of event is given then it can easily find the probability. For example see the calculator given in the page. Probability Calculator involves calculators like permutation calculator, single event probability calculator, P value calculator two tailed. Below you can see the list of all the calculators which are comes under in this topic. Friends, today we all going to learn the basic concepts behind probability and how probability calculator helps in probability calculations. First question comes in our mind is that what is probability? Probability is used to find the number of occurrence of an event out of possible outcomes. Probability should always lie between 0 and 1. In simple mathematical manner, probability is a way of telling or expressing a knowledge that an event will occur or has occurred.

Probability theory plays an important role in various human activities that involves the analysis of a large set of data. Single Event probability: It is used to find the probability for a single event that occurs for an experiment. Example tossing a coin, single head or tail, expected results. Probability that event A occurs P(A) = n(A) / n(P). where, n(A) - number of events occurred n(P) - number of possible outcomes. Probability that event A does not occur P(A') = 1 - P(A). where, P(A) is the probability of single event A. Multiple-event probability: it is used to find the probability for multiple events that occurs for an experiment. Two coins are tossed at the same time. Unexpected result. Probability that event A occurs P(A) = n(A) / n(p). where, n(A) - number of event occurred in A n(p) - number of possible outcomes Probability that event B occurs P(B) = n(B) / n(p). where, n(B) - number of event occurred in B n(p) - number of possible outcomes Probability that event A does not occur P(A') = 1 - P(A). Probability that event B does not occur P(B') = 1 - P(B). Probability that both the events occur P(A ? B) = P(A) x P(B). Probability that either of event occurs P(A ? B) = P(A) + P(B) - P(A ?(B). Conditional Probability P(A | B) = P(A ? B) / P(B). The probability of an event occurring given that another event has already occurred is called a conditional probability. The Probability Calculator computes the probability of one event, based on probabilities of other related events.

This calculator solves problems that used the three basic rules of probability which are the subtraction rule, addition rule, and multiplication rule. Online Free Tutoring is a tutoring which help you to solve the maths problems and also tells you that how to arrive an answer. Free Online Math tutor chat are available at any time and at any place for all grade, college and university level students to provide math homework help. So the other number is x+ 1 that is 18 + 1 =19. hence two consecutive numbers are 18 and 19. Online free math tutor will explain you all the fundamental of word problem and if you use free online tutoring math then you will exactly know how to crack word problems. Free online tutoring math service is a good way to learn apprentice math problems. Online free math tutors illustrate all the things from basic to higher level.
