Respuesta :
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.

Probability
Probability is the likeliness of happening an event. It is calculated when we are unsure about the outcome of an event.
How to calculate the probability:
We are given that there are 5 guppies , 4 platyfishes and 3 rasboras in the tank and an employee randomly selects a fish from the tank and we have to find the probability that the selected fish is platyfish.
The formula of probability is
=number of events/number of items possible
=number of platyfishes/number of fishes in the tank
=4/12
=1/3
Hence the answer of this question is 1/3.
It concludes that the probability of a smaller event is less and the probability of a larger event is larger.
