#### DESCRIPTION:

Find the probability of pulling a yellow marble from a bag with 3 yellow, 2 red, 2 green, and 1 blue. The instructor actually draws the marbles here. That isn't necessary, but feel free to do whatever you need to to "visualize" the question.

#### OVERVIEW:

**
1. HSS.CP.B.7 :** Apply the Addition Rule, P(A or B) = P(A) + P(B) - P(A and B), and interpret the answer in terms of the model..

**
2. HSS.CP.B.8 :** Apply the general Multiplication Rule in a uniform probability model, P(A and B) = P(A)P(B|A) = P(B)P(A|B), and interpret the answer in terms of the model..

**
3. HSS.CP.B.9 :** Use permutations and combinations to compute probabilities of compound events and solve problems.
