Question

here is another...I am playing a dice game where if I roll the sum of the numbers being a prime number I win otherwise you would win. Is thi game fair? and how do you figure out the sample space?

Answer 1

Prime numbers available
2: 1+1
3: 1+2, 2+1
5: 1+4, 2+3, 3+2, 4+1
7: 1+6, 2+5, 3+4, 4+3, 5+2, 6+1
11: 5+6, 6+5
out of 36 possible ways to get a sum, there are 15. Therefore, the game is UNFAIR in the other person's favor (since there are not 18 ways to win)

Answer 2

great that was my answer it gives the other person 22 ways

Answer 3

thanks
