Answer 1

[AI-generated answer — Bot GPT 3.5]

There are a total of 10 numbers in the list. Out of these numbers, 5 are even (4, 10, 12, 18, 20).

Therefore, the probability of picking an even number is:
Number of favorable outcomes (even numbers) / Total number of outcomes
= 5/10
= 1/2

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