How many candies with the letter B are in this candy jar?  
How long is the average television commercial?
How many words are in a Shakespearian sonnet?
How many people in your school have brown hair?

It can be very time consuming to count to find the answers to these questions. But, there are quicker methods to finding out the approximate answers.

One way to find out the approximate answer is to use simple random sampling. Simple random sampling helps us to draw inferences about a population with an unknown characteristic that interests us.

Simple random sampling: A sample is chosen randomly from the population. Every object in the population has an equal chance of being chosen as part of the sample.

Inferences: A conclusion reached on the basis of evidence and reasoning.
