Cards are drawn from a well-shuffled deck of 52 without replacement. Find the probability for each event below:
a) Drawing an ace or a black card.

Suppose that \(\mathscr{A}\) is the event of drawing an ace, while \(\mathscr{B}\) is the event of drawing a black card.
Then the probability of \(\mathscr{A\cup B}\), drawing a ace or a black card is
\(\mathcal{P}(\mathscr{A})+\mathcal{P}(\mathscr{B}) -\mathcal{P}(\mathscr{A\cap B}) \) Can you find the value of those?
