There are 10 items, you will pick three items out of these 10, what is the probability that the items you pick contain the most expensive 2 of the 10?
How would you solve this problem? I don't really know where to start.
My tentative solution is 2/10 + 1/10 + 8/10 The first 2/10 is the probability of picking one of the two most expensive item, then 1/10 indicates picking the other one of the two, then 8/10 indicates everything else is fair game.
I think I'm totally going about this the WRONG way. How would you solve it? Probability problems give me migranes! .......
