poker 5 card rules

the probability of a deck of cards question?

Hi all I play poker with my friends, and we've made ​​up their own rules and want to know which hands are more difficult to obtain. That is why I wanted to know how to mathematically determine the following questions. They are involved with the normal 52 cards deck (no Jokers), and plays poker 5 cards. If I'm given 5 cards out of a possible 52: 1) What is the probability of getting 2 out of 5 cards of the same suit (it means hearts, spades, etc.) 2) What is the probability of getting 3 cards / 5, which are contiguous, eg (234 or JQK) I would like to know the answers to these and also how to work them out, thanks. I have a lot of these types of questions so if you could give me a method, however, a complex work out of the 5-card possibilities, I'll give you the best solution and hope. Thank you very much in advance for Question 1 should be 3 / 5 cards of the same land for forgiveness.

1) What is the probability of getting 2 out of 5 cards of the same suit (means hearts, spades, etc 100%. Since there are five cards and only four of them, you'll always be at least two cards of the same suit.
