October 19, 2010Use a tree diagram to figure this probability
out.If you flip a coin 4 times, what is the
probability of flipping heads, then tails, then heads, and then finally tails?

October 20, 2010Compute the compound probability if you are
using a standard deck of 52 cards (no jokers).1. What is the probability of drawing a red king,
then a face card, and then an even number card without replacing any of the cards?
2. What is the probability of drawing royal flush one card at a time without replacing any of the cards (hint: can be in any suit)?
October 25, 2010Graph each point on a coordinate plane.

October 26, 2010Find the range of the function f(x) = x – 6 for
the domain: {-2, 0, 5}
October 27, 2010Graph the function, by setting up a table,
plugging in at least three points for the domain, and then plotting your ordered pairs on the coordinate plane. (Hint: you don’t have to use -1, 0, and 1 as your domain; use multiples of 3 for simplicity.)
