A student walks to campus every morning and must cross a busy intersection. Sometimes the traffic light is red, causing a delay. Over 150150 days, the student records whether the light was red (11) or not (00) when they arrived. Explain why being stopped by the red light is a random process.

Problem 124Multiple Choice

A student walks to campus every morning and must cross a busy intersection. Sometimes the traffic light is red, causing a delay. Over $150$ days, the student records whether the light was red ( $1$ ) or not ( $0$ ) when they arrived. Explain why being stopped by the red light is a random process.

Because the student can always predict when the light will be red.

Because the occurrence of a red light is unpredictable and depends on factors outside the student's control, making it a random process.

Because the light is always red at the same time every day.

Because the student chooses when to arrive at the intersection.
