Question

A bag contains 12 pencils, 6 ball pens, and 2 sketch pens. Ronald takes out one writing object from this bag to note down some important information. What is the probability that a ball pen or a pencil is selected?

Answer 1

12 pencils, 6 ball pens, 2 sketch pens.

Simply add the pencils and ball pens together :)

12 + 6 = 18

So, the probability is 18 : 2

However, we can simplify this.

9 : 1
