The school bus Evie rides is scheduled to arrive at her stop at 8:20 a. m. each day. The table below shows the actual arrival times of the bus for several days that were randomly selected over the past few months. Based on these data, what is the probability that the bus will arrive at Evie's stop before 8:20 a. m. tomorrow? I have an answer I just want to know how other people would do it..
