Question 11 1 pts You are at a coffin convention (that welcomes vampires and non-vampires) with mirrored walls. You know that some vampires can be reflected in mirrors but that most can't; you estimate that 90% of vampires have no reflection. Also, there are some harmless people that can't be reflected in mirrors even though they are not vampires. You think Vampires are relatively rare. Your prior estimate is that just one percent of the 1,000 people at the well-lit convention are vampires. You carefully watch the mirrored walls and decide that there are 100 people at the convention that have no reflection. A charming and attractive person invites you to someplace quieter for a drink. You peek over the attractive person's shoulder and notice that it's just you in the mirror. You're partial to charming and attractive people though, so you try to calculate the probability that your potential date is a vampire based on what you've (not) seen in the mirror. If V is 'the person is a vampire," and R is 'the person has a reflection,' then what probability are you after? O P(R/V) O P(V/~R) O PMV O P(-R/V) O P(V/R)
