Much of data analysis involves interpreting proportions - lots and lots of related proportions. So let's recall the basics. It might help to start by reviewing the main rules from Data 8 (Chapter 9.5), with particular attention to what's being multiplied in the multiplication rule. For this question, assume we have a bag filled with 14 marbles: 6 blue marbles, 3 red marbles, and 5 yellow marbles. (a) Yash selects 2 marbles without replacement. What's the probability that the selected marbles have the same color? You can leave your solution in equation form.

(b) Yash selects 4 marbles with replacement. What's the probability that he sees at least 1 blue marble?
