A data analyst is reviewing sales records from a store over the past 12 months. The total sales are summarized in the following table:
Month | Sales ($) |
---|---|
January | 5000 |
February | 7000 |
March | 8000 |
April | 6000 |
May | 9000 |
June | 11000 |
July | 12000 |
August | 15000 |
September | 14000 |
October | 16000 |
November | 17000 |
December | 18000 |
If the analyst wants to determine the probability that sales in a randomly selected month will be greater than $10,000, what is the probability expressed as a decimal?
