I am having problems with practice problem, and I need help? Thank you

The GREEN traffic light immediately switches “off” and the AMBER traffic light switches “on” to begin to stop the traffic flow. The outputs remain in this state for 5 seconds.

The AMBER traffic light switches “off” and the RED traffic light switches “on.” The outputs remain in this state for 5 seconds, to ensure that traffic has stopped before pedestrians begin to cross.

The WALK pedestrian light switches “on” and the RED traffic light remains “on.” Outputs remain in this state for 15 seconds, allowing pedestrians safe passage across the street.

The WALK pedestrian light switches “off” and the RED traffic light remains “on.” Outputs remain in this state for 5 seconds, to ensure that pedestrians are not still crossing the street when the traffic light changes from RED to GREEN.

The GREEN traffic light switches “on” and the RED traffic light switches “off.” Outputs remain in this state for at least 30 seconds to ensure a minimum amount of automotive traffic flow time even if the walk pushbutton is pressed to start the cycle again.
