Answer: The answer would be:
1/36
Explanation:
You would get this since you are trying to get both independent rolls that reset the chances again.
To get 3 first you would have a probability of 1/6.
For the probability of rolling 5 on the second roll would also be 1/6.
So to get the probability of getting both is 1/6*1/6=1/36
Hope this helps! [:
