Question

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)

Answer 1

There are 10 numbers in total in the list. Out of these, 5 are even numbers (2, 4, 10, 12, 18).

Therefore, the probability of getting an even number is 5/10 = 1/2.

So, the probability of getting an even number when picking a number from the list is 1/2.
