Graphical Representation of Beta Distributions - Set 1

This plot is an example of the Beta Distribution with parameters alfa=1 and beta=1. The density function is a horizontal straight line.

This plot is an example of the Beta Distribution with parameters alfa=0.75 and beta=0.75. The density function shows a U-shaped pattern.

This plot is an example of the Beta Distribution with parameters alfa=1 and beta=2. The density function is a straight line with a negative slope.

This plot is an example of the Beta Distribution with parameters alfa=2 and beta=1. The density function is a straight line with a positive slope.
