**Introduction To Probability Calculator:**

A Probability Calculator is a tool that allows users to compute the probability of an event occurring based on the number of successful outcomes and the total number of possible outcomes. Probability is a measure of the likelihood of an event happening, expressed as a value between 0 and 1, where 0 represents impossibility, and 1 represents certainty. This tool provides a simple interface for users to input data and obtain the probability result.

## Formula For Probability Calculator:

The Probability Calculator employs a fundamental probability formula to calculate the probability of an event. The formula used in this calculator is:

**Probability (P) = (Number of Successful Outcomes) / (Total Number of Outcomes)**

Users provide the number of successful outcomes and the total number of outcomes, and the calculator computes the probability.

**Working of Probability Calculator:**

**Inputs:**

**Number of Successful Outcomes:**

Users input the count of favorable outcomes.

**Total Number of Outcomes:**

Users input the count of all possible outcomes.

**Calculation:**

Upon clicking the “Calculate Probability” button, the JavaScript code within the calculator retrieves the user’s inputs.

**Validation:**

The code ensures that both inputs are valid: the number of successful outcomes is a non-negative integer, and the total number of outcomes is a positive integer greater than or equal to one.

**Probability Calculation:**

If the inputs are valid, the calculator applies the probability formula to calculate the probability:

**Probability (P) = (Number of Successful Outcomes) / (Total Number of Outcomes)**It divides the number of successful outcomes by the total number of outcomes to obtain the probability.

**Display Result:**

The probability result is displayed on the webpage, rounded to four decimal places. The result appears in a clear and easily readable format.

**Conclusion:**

The Probability Calculator is a valuable tool for individuals looking to determine the probability of an event based on specific outcomes. It utilizes a simple formula to calculate the probability, providing users with a quick and accurate result. This tool is especially useful in various fields, including statistics, mathematics, and decision-making, where understanding and calculating probabilities are essential.
