2. For a probability space \((\Omega, \mathcal{F}, \mathbb{P})\), the definition of expected value for continuous random variables is given by:

\[
\mathbb{E}[X(\omega)] = \int_{\Omega} X(\omega) d\mathbb{P}(\omega)
\]

Using this result, prove the following:

- For random variables \(X\) and \(Y\) and scalar constants \(a\) and \(b\), we have \(\mathbb{E}[aX + bY] = a\mathbb{E}[X] + b\mathbb{E}[Y]\).
- The random variable 1, which is a degenerate random variable and is a constant, has expectation \(\mathbb{E}[1] = 1\).
