Two Question Quiz

You are given a quiz with two questions.
Here are the two questions:

1. The D train goes to Coney Island. True or False.

2. Coney Island is located in Brooklyn, New York. True or False.

You don't know the answer to each question. So you decided to take a wild guess. What is the probability that you will get both questions correct?

A = getting question 1 right

B = getting question 2 right

P(A) = 1/2

P(B) = 1/2

P(A and B) = P(A) • P(B)

P(A and B) = 1/2 • 1/2

P(A and B) = 1/4

You say?
