Offent she use her phone alarm to wake her up which can wake her up most of the time but not always. Based on the scenario, a graphical representation along with the conditional probability tables are given as follows: Bus Late? yes 0.2 no 0.8 On Time? yes 0.1 02 03 09 Over slept? Alarm bus, overs no On? yes, yes 09 yes, no 08 no, yes no, no 07 yes no alarm yes no 01 0.9 0.1 yes 0.1 09 no 0.9 01 a. Compute the probability that she was late today because of the public bus but not over- sleeping and alarm was on which could help her wake up on time. b. Compute the probability that she was late due to oversleeping but bus was not late.
