Carlos has a spinner that is divided into 3 equal-sized sectors numbered from 1 to 3, and a number cube labeled from 1 to 6. He will spin the arrow of the spinner and roll the number cube one time. What is the probability that the arrow will land on a sector labeled 3, and the number cube will land on a number less than 3?

• $\frac{1}{9}$

• $\frac{2}{9}$

• $\frac{2}{3}$

• $\frac{5}{6}$
