A stoplight has the following cycle: green for 50 seconds, yellow for 4 seconds, and red for 62 seconds. If you arrive at the light 50 times, predict how many times you will have to stop and wait more than 4 seconds. About 27 times About 50 times About 25 times About 2 times

Let's break down the stoplight cycle! The full cycle lasts for 116 seconds (50 seconds green + 4 seconds yellow + 62 seconds red). During this cycle, when the light is red for 62 seconds, you will have to stop and wait. So essentially, every time you arrive at the light during the red phase (after the yellow), you will wait at least 62 seconds, meaning you have to stop and wait more than the 4 seconds about 27 times out of 50 arrivals. If you arrive randomly in this cycle, the probability of hitting a red light is pretty high since it lasts longer than the other colors. Statistically, getting caught at red will generally happen more than 50% of the time, resulting in approximately 27 halts. Need to brush up on your traffic light timing strategies!
