Probability Practice Test

A fair six-sided die is rolled once. Event $A$ is "the result is even" and event $B$ is "the result is greater than 4." What is $P(A\mid B)$?

A fair six-sided die is rolled once. Let event $A$ be “the result is a multiple of 3” and event $B$ be “the result is even.” What is the probability that the roll is in $A \cup B$?
