What is the probability of getting two numbers that have a sum of 5 on the spinner?
A. two-ninths

D. four-ninths

D. four-ninths
The only two numbers with a sum of 5 are 2 and 3. The probability of getting a 2 on the first spin is $\frac13$ and the probability of getting a 3 on the second spin (after getting a 2 on the first spin) is also $\frac13$. So, the probability of getting two numbers that have a sum of 5 is $\frac13 \cdot \frac13 = \boxed{\textbf{(C) }one-sixth}$.
