Will give ! : )

an employee at a pet shop randomly selects a fish from a tank where there are 5 guppies, 4 platyfishes, and 3 rasboras.

what is the probability that the selected fish is a platyfish?

enter your answer as a fraction, in simplified form, in the box.

There are 12 fish total in the tank, and we are looking for the probability that you will get a platyfish , which there are 4 of. 
So, you take 4, and put it over 12.

       4            1
   =
     12             3
Finally, you'll reduce 4/12 to 1/3. 
So, 1/3 is your answer.

To answer the problem above, take note that for negative numbers, the bigger the numerical equivalent of the number without considering the sign, the smaller its value is. From the given above, the order from least to greatest is: -3930, -0.7, 9.73, and 92.
