Question 145329: bobby has a game where he uses a six sided die. Each side of the die has one of the following numbers: 0, 2, 4, 6, 8, 10. In this game, one round = 1 roll when bobby rolls the die, he scores the number of points that show up on the die. If he rolls a "10" he gets to roll again in the same round and add the second roll score to the first. For example on his first roll he rolls a 10 and rolls again to get a 4-- his score is 14.
What is the probability that bobby will score each of the following on his first "round"? 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. what is the probability that if the first roll is a 10 and with his free roll, the resulting score will be each of the following: 10, 12, 14, 16, 18, 20.

What is the probability that bobby will score each of the following on his first "round"? 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. what is the probability that if the first roll is a 10 and with his free roll, the resulting score will be each of the following: 10, 12, 14, 16, 18, 20.
-----------------
The probability associated with each of 0,2,4,6,8 is (1/6)
-----------------
10,12,14,16,18,20 each have probability = (1/6)(1*6) = 1/36
