The Exponential Distribution Calculator is a mathematical tool used to compute probabilities and statistics related to the exponential distribution. The exponential distribution is a continuous probability distribution that describes the time between events in a Poisson process, where events occur at a constant average rate and are independent of each other.

Understanding the Exponential Distribution

The probability density function (PDF) of the exponential distribution is given by:

\[ f(x;\lambda) =
\begin{cases}
\lambda e^{-\lambda x} & \text{for } x \geq 0 \\
0 & \text{for } x < 0 \end{cases} \]

Where:

  • \(f(x;\lambda)\) is the probability density function.
  • \(\lambda\) (lambda) is the rate parameter, which is the average number of events per unit time.
  • \(e\) is the base of the natural logarithm (approximately 2.71828).
  • \(x\) is the random variable representing the time between events.

The Exponential Distribution is widely used in fields like reliability engineering, queuing theory, and survival analysis.
