Answer:

6/11

Step-by-step explanation:

write down all the factors of 24:

1,2,3,4,6,8,12,24.

now write down all the possible sums you can get by rolling 2 dice:

2,3,4,5,6,7,8,9,10,11,12.

Now, see which numbers appear in both the lists we created:

2,3,4,6,8,12. There are 6 numbers that can be the sum and also the factor of 24.

Therefore the probability is: 6/11 (number of numbers in the 2nd list)

Hope this helps.

Good Luck
