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.
There are 6 even numbers in the list - 2, 4, 10, 12, 18, 20.
Probability of getting an even number = Number of favorable outcomes / Total number of outcomes
Probability = 6/10 = 3/5
Therefore, the probability of getting an even number is 3/5.
