Probability problem.

Suppose that you are dealt a hand of 6 cards from a standard deck of 52 playing cards.

a) What is the probability that you are dealt no jacks and exactly 1 diamond?
b) What is the probability that you are dealt no more than 2 spades?
c) What is the probability that you are dealt at least 2 sevens and at least 2 fives?
