The sample space for a roll of two number cubes is shown in the table. A 6 by 6 table of ordered pairs is shown. • A single ordered pair appears in each cell of the table. In row one, the first element of each ordered pair is 1. This pattern continues through row 6, where the first element in each ordered pair is 6. • In column one, the second element in each ordered pair is 1. This pattern continues through column 6, where the second element in each ordered pair is 6. What is the probability that the roll will result in both numbers being the same? A. start fraction 1 over 6 end fraction B. one-third C. start fraction 7 over 18 end fraction D. Start Fraction 2 over 3 End Fraction
