A number from the list {2, 4, 5, 7, 9, 10, 12, 15, 18, 20} will be picked at random. what is the probability of getting an even number? Write your answer in the simplest form of fraction.

Answer 1

There are a total of 10 numbers in the list, out of which 5 are even numbers (2, 4, 10, 12, 18).

Therefore, the probability of getting an even number = Number of even numbers / Total number of numbers
= 5/10
= 1/2

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

Answer 2

wrong

Answer 3

Apologies for the mistake. Let's correct that.

There are a total of 10 numbers in the list, out of which 5 are even numbers (2, 4, 10, 12, 18).

Therefore, the probability of getting an even number = Number of even numbers / Total number of numbers
= 5/10
= 1/2

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