Answer

Calculate the probability of getting an even sum: $\frac{6}{12} = \boxed{0.5}$

Steps

Step 1 ：Create a table to represent the sample space of rolling the die and spinning the spinner: $\{(1, 3), (1, 6), (1, 9), (2, 3), (2, 6), (2, 9), (3, 3), (3, 6), (3, 9), (4, 3), (4, 6), (4, 9)\}$

Step 2 ：Calculate the probability of getting an even sum: $\frac{6}{12} = \boxed{0.5}$
