The two-way table summarizes information about eye color and gender in a random sample of 200 high school students.
\[\begin{array}{|c|c|}\hline & \text{Male} & \text{Female} & \text{Total} \\ \hline \text{Blue} & 21 & 29 & 50 \\ \hline \text{Brown} & 35 & 40 & 75 \\ \hline \text{Green} & 14 & 21 & 35 \\ \hline \text{Hazel} & 12 & 23 & 35 \\ \hline \text{Other} & 2 & 3 & 5 \\ \hline \text{Total} & 84 & 116 & 200 \\ \hline \end{array}\]
Is there an association between eye color and gender in this group of students? Support your answer with an appropriate graphical summary of the data.

A: student is male and event

B: student has blue eyes.

\(\text{Gender}\ \text{Eye color}\begin{array}{l|c|c|c}
& \text { Male } & \text { Female } & \text { Total } \\
\hline \text { Blue } & & & 10 \\
\hline \text { Brown } & & & 40 \\
\hline \text { Total } & 20 & 30 & 50
\end{array}\)

Copy and complete the two-way table so that events A and B are independent.

If you choose a student at random, what is the probability that the student eats regularly in the cafeteria and is not a 10th-grader?
