Three cars arrive at an intersection at about the same time that a pedestrian crosses one of the roads. Who has the right of way here?

A vehicle must yield to pedestrians in a marked or an unmarked crosswalk. And at an intersection without signs or signals, each vehicle must yield to the one on its right. Therefore, Car A must yield to Car B, Car B must yield to Car C, and Car C must yield to the pedestrian. [Intersections, 3. Turns and Intersections, Oregon Driver Manual]
