About this app

Continuous probability distributions:
- Normal (Gaussian)
- t (Student's t)
- Chi-Squared
- F
- Exponential
- Gamma
- Beta
- Log-normal
- Weibull
- Uniform

Discrete probability distributions:
- Binomial
- Poisson
- Pascal (Negative Binomial)
- Geometric
- Hypergeometric
- Discrete Uniform

You can now calculate confidence intervals for "Both", "Middle", "Lower" and "Upper" tails. For example, if you want to find the 95% confidence interval of a Normal Distribution:
1. first select "Normal" distribution and select "Middle"
2. then enter "0.95" on the right side of the probability values
3. From and to values will be automatically calculated for you (-1.96, 1.96 in this case)

What's new

The user interface was flipped from right to left when the system language is a right to left language. This release prevents flipping since the app only supports English language.
