# PROBABILITY CALCULATOR

## About probability calculator

Probability calculator provided on this web page is a tool which can be used  to find probability of an event.

## Why do people need this calculator?

When people want to find probability of an event,  they will use the appropriate formula. When students have lengthy problems in math, as a part of the problem, students may have to find probability of a particular event.

While solving a lengthy  problem, doing the above work as a part of the problem will annoy them. At that time, students can use this online probability calculator to find probability of an event.

## Using the calculator in solving word problems

When people do preparation of solving word problems in math, they may have to spend time to get idea on "How to solve". In some situations,  they may have to find probability of a particular event .While they are thinking a lot to solve the word problem, they would not like to spend time to do the above work as a part of the word problem.

Because, when people do word problems in math , they have to do this work separately and they might do some careless mistakes in finding probability. It will definitely disturb the solving of word problems.And also they would not be able to use regular calculators to find probability of an event. By using this online calculator, students will find much time to get idea of solving the word problems.

## Advantages of using this online calculator

Students have the topic "Probability" in both school level and college level statistics. They may have to do lots of problems on this topic. In most of  the problems on this topic, they may have to find probability of an event. Students would find answers for the questions as directed in the question. But they would not be sure, whether the answer they have received is correct or incorrect. At that time, they can use this online calculator to verify their answer.

## Probability of event - Formula Let us consider an example to have better understanding of the probability formula given.

Question : If a coin is tossed thrice, find the probability of getting two heads.

Solution:

Let "A" be the event of getting two heads.

S = { HHH, HHT, HTH, THH, TTT, TTH, THT, HTT}

A = { HHT, HTH, THH}

n(S) = 8 ---> Total no. of possible outcomes

n(A) = 3 ---->No. of favorable outcomes.

Then,  Probability of A = n(A) / n(S)

P(A) = 3/8
