A Pig in a Poke
RAY: The question was, what did Zeke and Zack say to the farmer that got them hired?
TOM: And the answer is, 'We'll be here tomorrow.'
RAY: Exactly. 'We'll be here tomorrow.' Here's why: Zeke's car starts 80% of the time, that's eight times out of ten, which means two times out of ten it doesn't start. Zack's car starts 70% of the time which means three times out of ten his car does not start.
So the two cars together don't start two times out of ten and three times out of ten, which means the probability of both cars not starting is six out of a hundred which is six percent. They're going to be there 94% of the time.
So who is our winner?
TOM: The winner this week is John Burton from New Market, Tennessee, and for having his answer selected at random from among all the correct answers that we got, John's going to get a $26 gift certificate to the Shameless Commerce Division at cartalk.com with which he can get one of our brand-new green and black endangered species T-shirts.
RAY: What's endangered around here?
TOM: The famous Massachusetts grease monkey!
RAY: Interestingly, he looks like a cross between you and Bonzo the chimp.
TOM: Hey, don't insult the chimp, he could be listening.
RAY: Congratulations, John!
