The [img]https://help.geogebra.org/hc/article_attachments/17121000589213[/img] [i]Distribution Tab[/i] allows you to easily calculate and graph a variety of probability distributions. [br]Just select the distribution you want to work with from the list available in the drop down menu (e.g. Normal, Binomial) and [i]GeoGebra [/i]will graph it for you. Then, you can adjust the parameters of the distribution in the adjacent text boxes.
