A study in Sweden looked at former elite soccer players, people who had played soccer but not at the elite level, and people of the same age who did not play soccer. Here is a two-way table that classifies these individuals by whether or not they had arthritis of the hip or knee by their mid-50s.
\(\begin{array} {lc} & \text{Soccer experience} \ \text {Arthritis} &\begin{array}{l|c|c|c|c} & & & \text { Did not } & \\ & \text { Elite } & \text { Non-elite } & \text { play } & \text { Total } \\ \hline \text { Yes } & 10 & 9 & 24 & 43 \\ \hline \text { No } & 61 & 206 & 548 & 815 \\ \hline \text { Total } & 71 & 215 & 572 & 858 \end{array} \end{array}\)
Suppose we choose one of these players at random. What is the probability that the player has arthritis?

In 1912 the Titanic struck an iceberg and sank on its first voyage. Some passengers got off the ship in lifeboats, but many died. The following two-way table gives information about adult passengers who survived and who died, by class of travel.
\(\begin{array} {lc} & \text{Class} \\ \text {Survived} & \begin{array}{c|c|c|c} & \text { First } & \text { Second } & \text { Third } \\ \hline \text { Yes } & 197 & 94 & 151 \\ \hline \text { No } & 122 & 167 & 476 \\ \end{array}\\ \end{array}\)
Suppose we randomly select one of the adult passengers who rode on the Titanic. Define event D as getting a person who died and event F as getting a passenger in first class. Find P (not a passenger in first class and survived).
