Hey guys, I need help with a few questions I have to do for an assignment.
1. Radio and television stations in the USA and Canada have names that are basically four letter words. These words must begin with a K, a W, or a C and may use a blank letter as the last letter. For instance both WHO and CKLW are acceptable names.
a) How many such station names are possible?
b) How many of these are three-letter names (the last letter is a blank)?
c) How many of these names use the same letter throughout the name?
2. A bridge hand consists of 13 cards. How many bridge hands include 5 cards of one suit, 6 cards of a second, and 2 cards of a third?
Have to use combinations, permutations, or factorials for these. I don't even know where to start.
Thanks for the help in advance!
