Which conclusion can be drawn from this graph? 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.
About half of the time, the traffic light is red when
Carlos leaves his neighborhood.
O 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.
O 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.
