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)

There are a total of 10 numbers in the list, and 5 of them are even numbers ({2, 4, 10, 12, 18}).

So, the probability of getting an even number is 5/10 or 1/2.

Therefore, the probability of getting an even number is 1/2.
