  • A probability question.?

    I was wondering if someone could help my solve this sample problem, so that I could do the rest of the homework myself:

    To select 3 members to be responsible for setting up their sound system, the names of 6 members of the Rocky Mountain Mud Flats Band are placed in a hat and three names are drawn. Three of the 6 members are singers. What is the probability that (a) exactly 2 singers will be selected? (b) at least 1 singer will be selected? (c) no singers will be selected?

    Of course, if someone wants to do the entire homework for me. They are more than welcome to.

  • At what point do I need to register my business?

    I'm trying to start a scrappy business of buying low-or free-on craigslist (or similar websites) and selling them at a markup. It's gonna be a really small thing, do I need to register it and do all that tax and stuff?
