Hello friends once again I am here, to explain you few mathematics topics and to tell you how you can use online tools for solving different mathematical problem online. Today we will discuss few things about probability and its calculator with benefits of free online math chat. Probability, you always use this term like probably i will come to your house today or probably this will happen, etc.
In general, probability is used to describe the state of mind towards some proposition and we are not concerned about the truth. It usually shows, will a specific event occur. In mathematics, probability is defined as: total number of successful events divided by the total number of possible events. It is directly proportional to how possible a event will occur. Greater the probability of an event, the more certain we are that the event will occur. So, we can say that, it is a measure of likeliness that a random event will occur. The probability for single event is given by:
probability of event A that occurs P(A) = n(A)/ n(S).
probability of event A that does not occur(A’)= 1 – P(A).
in the same way formula is given to calculate probability of multiple events.
Probability of event A that occurs P(A)= n(A)/n(s).
Probability of event A that will not occur P(A')= 1- P(A).
probability of event B that occurs P(B)= n(B)/n(S).
probability of event B that will not occur P(B') = 1 – P(B).
probability that both events occur P(A ∩ B) = P(A) * p(B).
Here n(A)= P(A) + P(B) – P(A ∩ B).
There is another formula for Conditional probability it is given as: P(A | B) = P(A ∩ B)/ P(B). where n(A) – number of event occurrence in event A,
m(B) – number of occurrence in event B,
n(S)- total number of possible outcomes.
There are lot of formulas to keep in mind if you have to solve any probability question. But, their is an easy way also, Probability Calculator it is a calculator developed to solve all the probability questions directly, and with its help you can solve all type of probability question. Probability Calculator will solve all the problems using basic rules of probability – the subtraction rule, addition rule, multiplication rule.
