Use the Addition Rule for Disjoint Events
-The distribution of Bachelor's degrees conferred by a university is listed in the table. Assume that a student majors in only one subject. What is the probability that a randomly selected student with a Bachelor's degree majored in Physics or Philosophy? Round your answer to three decimal places.
$\begin{array}{l|c}
\text { Major } & \text { Frequency } \
\hline \text { Physics } & 225 \
\text { Philosophy } & 208 \
\text { Engineering } & 86 \
\text { Business } & 176 \
\text { Chemistry } & 222
\end{array}$

A) $0.472$
B) $0.528$
C) $0.245$
D) $0.227$

Quizplus · Accepted Answer

The probability of majoring in Physics is 225/817 and the probability of majoring in Philosophy is 208/817. Since these events are disjoint, the probability of majoring in Physics or Philosophy is 225/817 + 208/817 = 433/817 ≈ 0.472.
