\begin{tabular}{l} 18. Rzucamy dwa razy symetryczną sześcienną kostka do gry. Oblicz prawdopo- \\ dobieństwo zdarzenia, że w pierwszym rzucie wypadła liczba oczek: \\ a) niepodzielna przez 4, \\ \hline b) co najmniej o 2 mniejsza niż w drugim rzucie. \\ \hline\end{tabular}

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? \( \begin{array}{llll}\text { a. } 16 & \text { b. } 8 & \text { c. } 10 & \text { d. } 12\end{array} \)

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?

2. In a small class, there are 8 men and 3 women. A group of 2 men and 1 woman is chosen to do a project together. How many different possible groups can be formed? \( \begin{array}{llll}\text { a. } 168 & \text { b. } 84 & \text { c. } 31 & \text { d. } 42\end{array} \)

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

If you flip two coins, what are the possible outcomes for the combined events?
