	A probability question which resulted from a game of Yahtzee		2005-12-31
		Robert pose la question : Could someone please assist me with this probability question which resulted from a game of Yahtzee we were playing in Melbourne, Australia on our holidays. The object on this turn was to throw a “large straight” which is 5 numbers in sequence from 5 dice numbered 1 – 6. A player initially throws all 5 dice and then selects those dice they want to throw again for a further two more times. In this instance the player on their first throw, threw a 1,2,3,4 and 6. Question:- What is the respective probabilities of gaining a straight if they were to – a) put back say the 6 and try and throw a 5 on the two further throws or….. b) put back the 1 and 6 and try and throw a 1 and 5 or 5 and 6 on the two further throws bearing in mind that if one of the numbers was a 5 on the second throw they could hold that number and try for a 1 or 6 on the third throw. I would be most appreciative if someone could assist in showing me how to calculate the probabilities particularly in the second instance (b). Penny Nom lui répond.
