If you toss a die twice, what is the sample space if you want to restrict the results to only the ones

where adding the results of the two throws together equals seven? For example, if you get 1 on the first toss and 6 on the second toss these two tosses meet the criteria.

A. S = {(1,6), (2,5), (3,4)}

B. S = {(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)}

C. S = {7}

D. S = {2,5), (5,2), (1,6), (6,1)}

E. S = (1,6), (2,5), (3,4)
