I would be really thankful for any hint
Let $x_1,\dots x_n$ be a sample from a geometric distribution with probability parameter $\theta$
The likelihood is given by $L(\theta\mid x_i, \dots, x_n)=\prod_i f(x_i\mid \theta)$ Assume we have observed a sample of size n=5 with values $x_i=5,6,9,5,4$. Specify a) an informative prior, (b) and uninformative prior, and determine the posterior distribution for each setting. Make a plot of prior, likelihood and posterior distribution.
