Help with Combinations / Permutations?

From a shuffled deck of 52 cards how many ways could you be dealt five cards containing 2 face cards, 2 aces and a five? A bag contains 25 marbles of which 6 are blue. How many ways are there of choosing three marbles of which at least one must be blue? What is the eighth term in the expansion of (x-(1/x))^16?
