How to Describe Probability

The video tutorial explains how to describe the probability of selecting a green pen from a carton containing different colored pens. It begins by introducing the problem and explaining that all pens are equally likely to be selected. The tutorial then calculates the probability of selecting a green pen, which is 1 out of 18, and describes this probability on a scale from impossible to certain, concluding that it is unlikely to select the green pen.

What is the total number of pens in the carton?

• 15

• 18

• 20
