From the set {1, 2, 3, 4, 5}, what is the probability of selecting an even number?

Explanation:
Probability is the ratio of favorable outcomes to total outcomes when every outcome is equally likely. In this set, the even numbers are 2 and 4, so there are 2 favorable outcomes out of 5 total outcomes. That gives 2/5 = 0.4. With five equally likely choices, having two even numbers means the chance of picking an even number is 0.4.
