We draw a card from a Spanish deck of \(40\) cards and we consider the events: \(\mathrm{A}\) "Draw an even number," and \(\mathrm{B}\) "Draw a card greater than \(5\)." What is the probability of the \(\textbf{intersection}\) of events \(\mathrm{A}\) and \(\mathrm{B}\) \( (\mathrm{A}\cap \mathrm{B})\)?
