One specific prior discussed in the previous lecture is the Beta distribution, which was then demonstrated in a scenario with a Bernoulli statistical model. Which of the follwing statements is/are true about the Beta distribution, written as \textsf{Beta}(\alpha , \beta ) \propto p^{\alpha -1}(1-p)^{\beta -1}?

The Beta distribution is very suited to models where our parameter represents a probability due to its support being [0, 1].

The Beta distribution is very suited to models where our parameter represents a probability due to its maximum always being close to \frac{1}{2}.

The Beta distribution is very suited to models where our parameter represents a probability because multiplying it by p or 1-p simply involves incrementing the respective parameter.

All three statements are true about the Beta distribution.
