In the four quarters of 2013, denoted by $$Q_1$$, $$Q_2$$, $$Q_3$$ and $$Q_4$$, Company C hired the same number of employees in $$Q_2$$ as in $$Q_1$$ and twice as many employees in $$Q_3$$ as in $$Q_2$$. The number of employees hired by the company in $$Q_4$$ was greater than the number of hired in $$Q_3$$; however, the number hired in $$Q_4$$ was also less than 3 times the number hired in $$Q_3$$. All of the employees were hired only once. If an employee is to be selected at random from all the employees hired during the four quarters, which of the following values could be the probability that the employee will be one who was hired in $$Q_4$$?

Indicate all such values.
