Burger preferences. A 2010 Survey USA poll asked 500 Los Angeles residents, "What is the best hamburger place in Southern California? Five Guys Burgers? In-N-Out Burger? Fat Burger? Tommy's Hamburgers? Umami Burger? Or somewhere else?" The distribution of responses by gender is shown below.
(a) Are being female and liking Five Guys Burgers mutually exclusive?
(b) What is the probability that a randomly chosen male likes In-N-Out the best?
(c) What is the probability that a randomly chosen female likes In-N-Out the best?
(d) What is the probability that a man and a woman who are dating both like In-N-Out the best? Note any assumption you make and evaluate whether you think that assumption is reasonable.
(e) What is the probability that a randomly chosen person likes Umami best or that person is female?
