Question 9 of 10

Calculate probability a person likes chocolate or vanilla.

‹ ›

\( \begin{array}{l}\textbf{In a survey of 1000 people, 600 like chocolate, 700 like} \\ \textbf{vanilla, and 450 like both. What is the probability that a} \\ \textbf{person likes either chocolate or vanilla?}\end{array} \)

Choose one option:

\( \frac{850}{1000} \) \( \frac{800}{1000} \) \( \frac{900}{1000} \)

Add counts, subtract overlap, divide by total students.

Use inclusion-exclusion to avoid double-counting students who like both flavors.
