Yeah, you're right, I did my integrals wrong. By symmetry, it is obvious that it should be 2/3, which is what those add up to. Thanks!

I was using y as the value function, with the bounds ranging over all possible values. When I do integrals with x*1 from 0 to 1, I still get 1/2.

Hello I have been struggling with a simple probability question. Homework Statement We are given that X is a uniformly distributed random variable on [0, 1]. After X is chosen, we take another uniform [0, 1] random variable Y (independent of X) and choose the subinterval that Y falls in. L...

I take that back; the integral is doable with a little manipulation. Damn machines...

I was doing this, but I think it is wrong: f_X(x) = \int^{\lambda=\infty}_{\lambda=0} \frac{\lambda^{x}}{x!} e^{-\lambda} \times \theta e^{-\theta \lambda} d \lambda Plugging this integral into Mathematica gives a really nasty output with a incomplete gamma function, and my TI-89T...

I am a little shaky on my probability, so bear with me if this is a dumb question... Anyway, these two random variables are given: X : Poisson (\lambda) \lambda : Exponential (\theta) And I simply need the marginal distribution of X and the conditional density for \lambda given a value for X...

How is finding exactly where oil is located not absurdly improbable? - And that is just one of many peculiar examples I heard on the History channel's show of him. FYI I did search "Edgar Cayce" before posting and did not find that post. Shame on me. From...

Let me start off by saying that I have never believed in miracles, superstition, pseudoscience, etc. In fact, it makes me sick to my stomache watching people on T.V. pretend to have such 'powers', or people who even talk about things defying reality. I recently watched a documentary on Edgar...
