My recollection is that for this to work you need to have all successes and no failures.

The first line of the solution states "We cannot use the bernoulli/beta shortcut here since the uniform distribution is only up to .5" I tried doing it using the shortcut and then just multiplying it by .5 at the end, and that gives me .375. What is different here?

So just to be sure I have it straight 
When we have uniform [0,1], the "regular" shortcut always works. If we have uniform [0, b], and we observe 0 claims, then it would be (regular shortcut)*b. But since in this problem, we observe 1 claim (not all successes), we must work it from first principles. Is that accurate?

Exam C SOA Sample #15
I am struggling with the last part of the solution to this Bayesian credibility problem. My understanding is that I can get the probability during the year 9 by integrating the posterior density function over 0 to 0.5. Why is the solution's integrand the posterior density multiply by p? Thank you.
