Probability Distributions

Instructions:

To switch to the cumulative distribution function graph, click the blue line button. Click it again to revert to the probability density function. Next, select the tab to choose the desired probability distribution. Then, enter the necessary parameters, such as \(\mu\) and \(\sigma\). Afterward, select the area under the probability density curve. Below you can enter the values for the intervals.

Normal distribution function:

$$ f\left( x \right) = \frac{1}{\sigma \sqrt{2 \pi}} e^{- \frac{1}{2} \left( \frac{x - \mu}{\sigma} \right)^{2}} $$
