Sagot :

Answer:

C. 5/6

Step-by-step explanation:

There are 6*6=36 combinations you can roll

For each roll of one die, there is 1 roll of the other which will sum to 7, so there are 6 rolls which have a sum of 7

This means there must be 36–6=30 combinations which do NOT sum to 7

30/36=5/6 odds of not rolling a 7

Think about that logically. If there’s ONE second die result for each of the 6 first die results which is a 7 sum, then there must be FIVE that aren’t. So it would of course be 5/6
