Probability

We draw a card from a Spanish deck of $40$ cards and check the number on it. We consider the event $\mathrm{A}$: Draw an even number. 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 throw two dice and write down the difference of the scores obtained. Calculate the probability that the difference is zero.

We throw a die and write down the number obtained. Then, we consider the event $\mathrm{A}$: "Obtain a divisor of $6$." What is the probability of the event $\mathrm{A}$?

We throw a dice and a coin at the same time. You win if you get an odd number on the dice and a tail on the coin. What is the probability of winning?
