Fourth Option is correct.

Step-by-step explanation:

Since we have given that

let A be the event of drawing a blue marble.

We need to find the complement of event A i.e. represented by A'.

Complement of any set of all the outcomes that are not the event.

So, A' would be the event of not drawing a blue marble.

Hence, Fourth Option is correct.

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'.
