A bowl of M&M's consists of 100 blue M&Ms and 90 gold M&Ms. Assume that the M&Ms are all mixed up in the bowl, and that drawing out M&Ms is like simple random sampling.

a. Suppose you draw out 10 M&Ms. Write a math expression for the chance that you get more blue M&Ms than gold
b. Suppose you draw out 10 M&Ms and then I draw out 10 M&Ms from those that remain in the bowl. Find the chance that we get the same number of gold M&Ms. Yes, 0 is a number.
