Just a friendly reminder about assignments due this week:
Tuesday, February 16 - Graph Theory Group Project Drafts Due
Thursday, February 18 - Graph Theory Blog Post Due
Please don't forget about these due dates. Your group project drafts should be typed and placed in your google drive folders.
Last week, we started discussing some methods of counting. This week, we will continue with methods of counting on Tuesday with a discussion of combinations and permutations. With permutations, the order in which we choose things matters; with combinations, the order won't matter. A mneumonic to help you remember this is "committee - combination"; "president - permutation".
We will then move on to probability. You'll want to pay close attention to the vocabulary and formulas in this section. You should also make sure that you get comfortable with the notation. For example, P(E) is the probability that event E will occur.
Challenge Problem: In the game of Euchre 5 cards are dealt from a deck consisting of the 9, 10, J, Q, K, A of hearts, diamonds, spades, and clubs. The ideal hand would consist of both J's of a given color and the A, K, Q of one of the suits. (So, Jack of hearts, Jack of diamonds, and A, K, Q of diamonds would be one ideal hand, for example.) Find the probability of getting an ideal hand.
