in the game of poker, what is probability that a five-card hand will contain(a) a straight(five cards in unbroken numerical sequence)
(b) four of a kind
(c) a full house(three cards of one value and two cards of another value)

thanks you so much. I could not figure out.

2. Hm...I shall attempt this question...not sure if my answer is right though! >.<

(a) Sorry I don't understand what exactly is a straight cos I don't play poker...is J,Q,K,A,2 still considered a straight? If not, then my working is definitely incorrect. And the suits don't matter right?

$\displaystyle Probability = 1 \times \displaystyle{\frac{4}{51}} \times \displaystyle{\frac{4}{50}} \times \displaystyle{\frac{4}{49}}$

(b) $\displaystyle Probability = 1 \times \displaystyle{\frac{12}{51}} \times \displaystyle{\frac{11}{50}} \times \displaystyle{\frac{10}{49}}$
