There would be a 44.4% chance of either of these happening.
In order to find this we have to find out how many total possibilities there are. Because we have two die each with 6 sides, we have 36 total options.
Of those options, 12 of them start with either a 3 or 6, which are multiples of 3. So we can add 12 to our lists of successes.
Of those options, there are 4 more that don't start with those numbers, but do equal 7. (1 and 6, 2 and 5, 4 and 3, 5 and 2). So we can add 4 to our list of successes.
Knowing we have 12 and 4 successes, we can add them together to get 16. We can then divide that by the total options (36) to find the percentage above.
The rate of water level change per hour is 1.5 inches per hour. You can find it out easily by dividing the total time by the total level change. Hope this Helps:)
