It depends on what the shape is
The total number of all possible options is 40 (17 + 3 + 8 + 12) and number of options that fit the description of blue or large is 28 ( 17 + 3 + 8). Probability is represented as the number of desired options over the number of total options. This means the probability of a blue or large is 28 / 40 = 7 / 10.
As I can tell the tables are right but it would be a function since none of the x's repeat
