Probability

We draw two card from a Spanish deck of $40$ cards (without returning). Calculate the probability of getting two $2$ (deuces). Recall briefly Spanish $40$ card deck: each of four suits (colors) contains $1$, $2$, $3$, $4$, $5$, $6$, $7$, Jack $(10)$, Horse $(11)$ and King $(12)$.

We draw a card from a Spanish deck of $40$ cards and we consider the event $\mathrm{A}$: Draw a card less than $4$. What is the probability of the event $\mathrm{A}$? Recall briefly Spanish $40$ card deck: each of four suits (colors) contains $1$, $2$, $3$, $4$, $5$, $6$, $7$, Jack $(10)$, Horse $(11)$ and King $(12)$.

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 $\mathbf{\text{intersection}}$ of events $\mathrm{A}$ and $\mathrm{B}$ $(\mathrm{A}\cap \mathrm{B})$? Recall briefly Spanish $40$ card deck: each of four suits (colors) contains $1$, $2$, $3$, $4$, $5$, $6$, $7$, Jack $(10)$, Horse $(11)$ and King $(12)$.

We draw a card from a Spanish deck of $40$ cards and we consider the event $\mathrm{A}$: Draw a card less than $5$. What is the probability of the $\mathbf{\text{complementary}}$ event to the event $\mathrm{A}$? Recall briefly Spanish $40$ card deck: each of four suits (colors) contains $1$, $2$, $3$, $4$, $5$, $6$, $7$, Jack $(10)$, Horse $(11)$ and King $(12)$.
