Consider a Bayesian model with a parameter having a prior distribution ~ x² (4), and one observation Y|0 Poi(0). That is, has a chi-squared distribution with 4 degrees of freedom and Y|0 has a Poisson distribution with mean E(Y|0) = 0. s (a) Derive the marginal probability mass function (pmf) of Y. Note: this is the uncondi- tional pmf of Y. (b) Let V = Y + 2. Derive the pmf of V and show that it is a negative binomial pmf as
