A number from the list {2, 4, 5, 7, 9, 10, 12, 15, 18, 20} is to be picked at random. What is the probability of getting an even number? Write your answer in the simplest form of fraction.(1 point)
$$
The total number of choices is 10, and the number of even numbers is 5 (2, 4, 10, 12, 18).
Therefore, the probability of getting an even number is 5/10 or 1/2.
