Carlos thinks the traffic light to get out of his neighborhood is red more often than green. He decides to collect data to determine the probability of the light being red upon his approach. The graph of his long-run relative frequencies is shown. Which conclusion can be drawn from this graph?

About half of the time, the traffic light is red when Carlos leaves his neighborhood.
About 63% of the time, the traffic light is red when Carlos leaves his neighborhood.
If the true probability that the traffic light is red when Carlos leaves his neighborhood is 0.63, there would be no variation in the graph.
The probability that the traffic light is red when Carlos leaves his neighborhood cannot be determined from this graph because there is no pattern in a long series of traffic lights.
