Hello!
First of all we need to see all of the numbers she could roll to make a ten.
4+6
5+5
Let's look at the first equation. There is a 1/6 chance of rolling a four and a 1/6 chance of rolling a 6. This makes it a 1/36 chance of rolling these two numbers.
We have a 1/6 chance of rolling a 5 on both dice. This also gives us a 1/36 chance.
If we add these two probabilities together we get 2/36, or 1/18. This could also be written as 5.56%.
I hope this helps!
