Exponential Distribution Calculator

Use this calculator to find the probability density and cumulative probabilities for Exponential distribution with parameter $\theta$.

Exponential Distribution Calculator
Parameter $\theta$:
Value of A
Value of B
Probability X less than A: P(X < A)
Probability X greater than B: P(X > B)
Probability X is between A and B: P(A < X < B)
Mean = $1/\theta$
Variance = $1/\theta^2$
Standard deviation = $1/\theta$

Exponential Distribution

A continuous random variable $X$ is said to have an exponential distribution with parameter $\theta$ if its p.d.f. is given by $$ \begin{aligned} f(x)&=\theta e^{-\theta x}, x\geq 0;\theta>0. \end{aligned} $$
