Greg has a list of payments for goods brought every month for the years 2009,2010,2011, and 2012. He needs information from only the last three years. He can filter this by clicking on

"2009" and clicking "does not equal 2009"

Explanation:

The operator, 'does not equal', is a filtering operator used to exclude a specified attribute. The 'does not equal' operator is also used to provide the definition of the condition of the filter given that there are different values of two attributes

Therefore, given that there are only four years, and Greg needs the information of the last three years, which are, 2010, 2011, and 2012, the information for the year 2009 is to be excluded

Therefore, the correct option is; "2009" and clicking "does not equal 2009"
