A random sample of 88 U.S. 11th- and 12th-graders was selected. The two-way table summarizes the gender of the students and their response to the question "Do you have allergies?" Suppose we choose a student from this group at random.

\(\begin{array}{c|cc|c} & \text { Female } & \text { Male } & \text { Total } \\ \hline \text{ Yes } & 19 & 15 & 34 \\ \text{ No } & 24 & 30 & 54 \\ \hline \text{ Total } & 43 & 45 & 88\\ \end{array}\)

What is the probability that the student is female or has allergies?

\((a)\frac{19}{88}\)

(b)\(\frac{39}{88}\)

(c)\(\frac{58}{88}\)

(d)\(\frac{77}{88}\)
