In a small restaurant, 30% of the customers order pizza, 20% order pasta, and 50% order burger. Among those who order pizza or pasta, 60% order a non-alcoholic beverage, while 40% order an alcoholic beverage. Among those who order a burger, 20% order a non-alcoholic beverage, while 80% order an alcoholic beverage. All customers order exactly one dish and one beverage. (a) Draw a tree diagram corresponding to the described situation. (b*) What is the probability that a customer orders an alcoholic beverage? (c*) What is the probability that a customer who has ordered an alcoholic beverage has also ordered a burger?

Former pro football star O.J. Simpson was accused of murdering his wife. In the trial, a defense attorney pointed out that although Simpson had been guilty of earlier spousal abuse, annually only about 40 women are murdered by their partner per 100,000 incidents of partner abuse. But this was misleading. Every year it is estimated that about 5 of every 100,000 women in the US who suffer partner abuse are killed by someone other than their partner. Draw a tree diagram for women who suffer partner abuse. Calculate the following (round to 5 decimal places):a) What is the probability that a woman who suffers partner abuse will be murdered by their partner?b) What is the probability that a woman who suffers partner abuse will be murdered (by anyone)?c) What is the probability that a murdered woman who suffered partner abuse was murdered by their partner?
A certain company sends 50% of its overnight mail parcels via express mail service E1. Of theseparcels, 1% arrive after the guaranteed delivery time (denote the event late delivery by L).
