Question 1064965: Two fair number cubes are rolled. What is the probability of rolling a total greater than 6 OR rolling doubles?
Is the probability statement 21/36 + 6/36 or is it 21/36 + 3/36 ?
I don't know if you count the doubles only once, or in both statements
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! The total number of ways are 6+5+4+3+2+1=21, as you had.
Rolling doubles are 6 ways, 3 of which are included in the 21 above. 11,22,33 are not included.
Therefore, you count half of the doubles and don't count the other half, so it is the second, or 2/3 (24/36).
