comment Calculating expectation conditioned on a sigma algebra
Thanks Did. While I understand this, my thinking gets muddled when it comes to looking at sets and sigma algebras. Could you please help me out?

comment Calculating expectation conditioned on a sigma algebra
Hmmm, so is it $\sigma(Y)=\sigma(\{\phi,\Omega,\mathcal{B}{\{\omega\ge k\}},\mathcal{B}{\{\omega\le k\}}\})$? I am confused here...

@Did: I see. These are the atoms of $\sigma(Y)$, so the actual sigma algebra is the smallest sigma algebra generated from these atoms. Is that correct?
