A bin contains 8 green balls and 4 red balls. 5 balls are chosen from the bin, without replacement, and placed on the table. Which of the following sets can be used as the sample space for this experiment?
S1 = {more red than green balls chosen, more green than red balls chosen}
S2 = {exactly 1 red ball chosen, exactly 2 red balls chosen, exactly 3 red balls chosen, exactly 4 red balls chosen}
S3 = {odd number of green balls chosen, odd number of red balls chosen}
A. All of them are sample spaces.
B. S1 and S3 are the only sample spaces.
C. Only S3 is a sample space.
D. Only S2 is a sample space.
E. Only S1 is a sample space.
