Tony rolls a 6-sided die one time. The sample space for this experiment is S= {1, 2, 3, 4, 5, 6}. Assume there is an equal chance of rolling any of these numbers. Which of the following statements are true? Choose all that apply. The event "Tony rolls a 7" is E = {7}. The sample space is an equiprobable space. The event "Tony rolls an even number" is E = {2, 4, 6}. The event "Tony rolls a number between 1 and 6" is a certain event.
