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, out of which 5 are even (2, 4, 10, 12, 18).
So, the probability of getting an even number is 5/10 = 1/2.
