Role-playing games like dungeons & dragons use many different types of dice. suppose that a eight-sided die has faces marked 1, 2, 3, 4, 5, 6, 7, 8. the intelligence of a character is determined by rolling this die twice and adding 1 to the sum of the spots. the faces are equally likely and the two rolls are independent. what is the average (mean) intelligence for such characters?

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
