Hello,

I am a little shaky on my probability, so bear with me if this is a dumb question...

Anyway, the distributions of the two random variables are given:

[tex]X : Poisson (\lambda[/tex])

[tex]\lambda : Exp. (\theta)[/tex]

I simply need the marginal distribution of X and the conditional density for [tex]\lambda[/tex] given a value for X

I have all the equations for dependent distributions, but do not know how to apply them to this ostensibly easy problem...

Any help?
