Based on the data in this two-way table, which statement is true?

a: a flower being pink and a flower being a rose are independent of each other.

b: a flower being pink is dependent on a flower being a rose.

c: a flower being a rose is dependent on a flower being pink.

d: a flower being pink and a flower being a rose are the same.

 A: A flower being pink and a flower being a rose are independent of each other.

Step-by-step explanation:

We know that if event A and B are independent then

From  the given table we have ,

The number of pink flower = 60

Total number of roses = 315

Then ,the probability of selecting a pink flower :-

The total number of roses = 315

Then , the probability of selecting a rose :-

The number of pink roses = 20

Then , the probability of selecting a pink rose :-

Now, the product of probabilities of pink flower and roses will be

i.e.

Therefore, A flower being pink and a flower being a rose are independent of each other.

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'.
