Let Θ be a continuous random variable that represents the unknown bias (i.e., the probability of Heads) of a coin.

Question

a) The prior PDF fΘ for the bias of a coin is of the form

fΘ(θ)=aθ9(1−θ), for θ∈[0,1],

where a is a normalizing constant. This indicates a prior belief that the bias Θ of the coin is
