The city bus is scheduled arrive at Evie's stop at 7:20 a.m. each morning. The table below shows the actual arrival times randomly taken from the past few months.
7:21 7:21 7:19 7:20 7:23
7:22 7:20 7:18 7:20 7:18
7:21 7:20 7:19 7:17 7:25
7:20 7:20 7:18 7:19 7:24
According to the table, what is the probability that Evie's bus will come before 7:20 a.m. tomorrow?
Station learning took place in class today. There were 8 probability questions hung up around the classroom. Students worked with selected groups to solve questions around the classroom. When they determined an answer, they wrote it on their sheet, put the answer on a post-it and stuck it to the chart paper. When a group completed all of the questions, they came to me to verify answers. Groups that had incorrect responses were sent back to the respective centers to retry.
