1. A box contains a \( \$ 1 \) bill, a \( \$ 5 \) bill, a \( \$ 10 \) bill, and a \( \$ 20 \) bill. A bill is drawn at random and not replaced. A second bill is then drawn. How many outcomes are possible? \( \begin{array}{llll}\text { a. } 16 & \text { b. } 8 & \text { c. } 10 & \text { d. } 12\end{array} \)

02. No lançamento de um dado, defina o espaço amostral e os eventos a) "ocorrência de número par"; b) "ocorrência de um número menor do que c) ""; d) "ocorrência de múltiplo de 3"; e) "ocorrência de um número menor do que um número maior do que e) zero e menor do que 7 ".

If you draw a card from a deck and do not replace it, what type of events does this represent when drawing a second card?

Suppose you play a slot machine where each wheel has four pictures: one bell and three fruits. Let's say the payoffs are the same: \( \$ 20 \) for three bells, \( \$ 5 \) for three of the same fruit, and \( \$ 2 \) for two bells and one fruit. What's the expected value of the game? \( \$ 1.32 \) \( \$ 1.22 \) \( \$ 0.83 \)

3. How many ways can four cards be selected from a standard deck of 52 cards? \( \begin{array}{llll}\text { a. } 168 & \text { c. } 31 & \text { d. } 424,350 & \text { b. } 6,497,400 \\ \text { c. } 812,175 & \text { d. } 270,725\end{array} \)

¿Cuantas diferentes permutaciones o acomodos se pueden realizar con los números \( 1,2,3 \) tomando DOS a la vez?
