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.
