During the past 6 months, Rebecca has been late to work 20 out of 125 days. Also, during that time, she encountered a traffic jam on 25 out of the 125 days. On any given day, the probability that she is late to work AND encounters a traffic jam is 0.35. Based on the information, which of the following can be concluded? A.O The probabilities of Rebecca being late to work and encountering a traffic jam are NOT independent, because 0.16 x 0.2 + 0.35 B.O The probabilities of Rebecca being late to work and encountering a traffic jam ARE independent, because 0.16 + 0.2 + 0.35 c.O The probabilities of Rebecca being late to work and encountering a traffic jam ARE independent, because 0.16 x 0.2 + 0.35. D.O The probabilities of Rebecca being late to work and encountering a traffic jam are NOT independent, because 0.16 +0.2 + 0.35
