Answer 1

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

STEP (1)

We have to know how many pets does the pet store have.

Look : 10 + 9 + 8 = 27

So the pet store completely have 27 pets.

_________________________________

STEP (2)

Mario randomly selects a pet :

$\frac{10}{27}$

Is the Probability of selecting a cat.

##############################

$\frac{9}{27}$

Is the Probability of selecting a dog.

_________________________________

STEP (3)

(( or )) in mathematics means plus (( + )) .

So the Probability of selecting a cat or a dog means :

$\frac{10}{27} + \frac{9}{27} = \frac{19}{27}$

STEP (4)

There's no STEP 4.
