What is the sample space of two 6-sided dice where the first number is less than 4? List your values from least to greatest

looks to me like you're throwing 3-sided dice

Apologies for that oversight. Here is the corrected sample space of two 6-sided dice where the first number is less than 4:

{(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6)}

Listed from least to greatest, the values are:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6)

The sample space of two 6-sided dice where the first number is less than 4 is as follows:

{(1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3)}
