Equally Likely Outcomes
My Notes
22. Consider the following events.
\begin{tabular}{|c|l|}
\hline Event & \multicolumn{1}{|c|}{ Description } \\
\hline\( O \) & The selected number is odd. \\
\hline\( S \) & The selected number is more than seventy. \\
\hline\( D \) & The selected number is equal to today's date. \\
\hline\( I \) & The selected number is less than twenty. \\
\hline
\end{tabular}
a. If the number of points to be earned for each event is 10,20,30, 40 , with the least points being assigned to the event with the greatest probablity, then how should the points be assigned?
0 \( \qquad \) s \( \qquad \) D \( \qquad \) \( T \) \( \qquad \)
b. What is the probability that you will win 20 points?
23. Suppose a game is to be played with the marble bag where points are awarded for the following events.
a. If two of the events happen at the same time, then you get the points assigned to both events. What is the probability that you win 40 points?
b. List the possible outcomes for carning 25 points.
c. What is the greatest number of points that can be earned for the selection of a single number and what selection would allow that to happen?
d. State the complement of events \( O \) and \( S \).
e. Find the \( P\left(D^{\prime}\right) \) and \( P\left(T^{\prime}\right) \).
